    Genome sequence of Aedes aegypti, a major arbovirus vector (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-19
    Description: We present a draft sequence of the genome of Aedes aegypti, the primary vector for yellow fever and dengue fever, which at approximately 1376 million base pairs is about 5 times the size of the genome of the malaria vector Anopheles gambiae. Nearly 50% of the Ae. aegypti genome consists of transposable elements. These contribute to a factor of approximately 4 to 6 increase in average gene length and in sizes of intergenic regions relative to An. gambiae and Drosophila melanogaster. Nonetheless, chromosomal synteny is generally maintained among all three insects, although conservation of orthologous gene order is higher (by a factor of approximately 2) between the mosquito species than between either of them and the fruit fly. An increase in genes encoding odorant binding, cytochrome P450, and cuticle domains relative to An. gambiae suggests that members of these protein families underpin some of the biological differences between the two mosquito species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2868357/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2868357/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nene, Vishvanath -- Wortman, Jennifer R -- Lawson, Daniel -- Haas, Brian -- Kodira, Chinnappa -- Tu, Zhijian Jake -- Loftus, Brendan -- Xi, Zhiyong -- Megy, Karyn -- Grabherr, Manfred -- Ren, Quinghu -- Zdobnov, Evgeny M -- Lobo, Neil F -- Campbell, Kathryn S -- Brown, Susan E -- Bonaldo, Maria F -- Zhu, Jingsong -- Sinkins, Steven P -- Hogenkamp, David G -- Amedeo, Paolo -- Arensburger, Peter -- Atkinson, Peter W -- Bidwell, Shelby -- Biedler, Jim -- Birney, Ewan -- Bruggner, Robert V -- Costas, Javier -- Coy, Monique R -- Crabtree, Jonathan -- Crawford, Matt -- Debruyn, Becky -- Decaprio, David -- Eiglmeier, Karin -- Eisenstadt, Eric -- El-Dorry, Hamza -- Gelbart, William M -- Gomes, Suely L -- Hammond, Martin -- Hannick, Linda I -- Hogan, James R -- Holmes, Michael H -- Jaffe, David -- Johnston, J Spencer -- Kennedy, Ryan C -- Koo, Hean -- Kravitz, Saul -- Kriventseva, Evgenia V -- Kulp, David -- Labutti, Kurt -- Lee, Eduardo -- Li, Song -- Lovin, Diane D -- Mao, Chunhong -- Mauceli, Evan -- Menck, Carlos F M -- Miller, Jason R -- Montgomery, Philip -- Mori, Akio -- Nascimento, Ana L -- Naveira, Horacio F -- Nusbaum, Chad -- O'leary, Sinead -- Orvis, Joshua -- Pertea, Mihaela -- Quesneville, Hadi -- Reidenbach, Kyanne R -- Rogers, Yu-Hui -- Roth, Charles W -- Schneider, Jennifer R -- Schatz, Michael -- Shumway, Martin -- Stanke, Mario -- Stinson, Eric O -- Tubio, Jose M C -- Vanzee, Janice P -- Verjovski-Almeida, Sergio -- Werner, Doreen -- White, Owen -- Wyder, Stefan -- Zeng, Qiandong -- Zhao, Qi -- Zhao, Yongmei -- Hill, Catherine A -- Raikhel, Alexander S -- Soares, Marcelo B -- Knudson, Dennis L -- Lee, Norman H -- Galagan, James -- Salzberg, Steven L -- Paulsen, Ian T -- Dimopoulos, George -- Collins, Frank H -- Birren, Bruce -- Fraser-Liggett, Claire M -- Severson, David W -- 079059/Wellcome Trust/United Kingdom -- 5 R01 AI61576-2/AI/NIAID NIH HHS/ -- R01 AI059492/AI/NIAID NIH HHS/ -- R01 LM006845/LM/NLM NIH HHS/ -- R01 LM006845-08/LM/NLM NIH HHS/ -- R37 AI024716/AI/NIAID NIH HHS/ -- UO1 AI50936/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2007 Jun 22;316(5832):1718-23.

    The B73 maize genome: complexity, diversity, and dynamics (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: We report an improved draft nucleotide sequence of the 2.3-gigabase genome of maize, an important crop plant and model for biological research. Over 32,000 genes were predicted, of which 99.8% were placed on reference chromosomes. Nearly 85% of the genome is composed of hundreds of families of transposable elements, dispersed nonuniformly across the genome. These were responsible for the capture and amplification of numerous gene fragments and affect the composition, sizes, and positions of centromeres. We also report on the correlation of methylation-poor regions with Mu transposon insertions and recombination, and copy number variants with insertions and/or deletions, as well as how uneven gene losses between duplicated regions were involved in returning an ancient allotetraploid to a genetically diploid state. These analyses inform and set the stage for further investigations to improve our understanding of the domestication and agricultural improvements of maize.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schnable, Patrick S -- Ware, Doreen -- Fulton, Robert S -- Stein, Joshua C -- Wei, Fusheng -- Pasternak, Shiran -- Liang, Chengzhi -- Zhang, Jianwei -- Fulton, Lucinda -- Graves, Tina A -- Minx, Patrick -- Reily, Amy Denise -- Courtney, Laura -- Kruchowski, Scott S -- Tomlinson, Chad -- Strong, Cindy -- Delehaunty, Kim -- Fronick, Catrina -- Courtney, Bill -- Rock, Susan M -- Belter, Eddie -- Du, Feiyu -- Kim, Kyung -- Abbott, Rachel M -- Cotton, Marc -- Levy, Andy -- Marchetto, Pamela -- Ochoa, Kerri -- Jackson, Stephanie M -- Gillam, Barbara -- Chen, Weizu -- Yan, Le -- Higginbotham, Jamey -- Cardenas, Marco -- Waligorski, Jason -- Applebaum, Elizabeth -- Phelps, Lindsey -- Falcone, Jason -- Kanchi, Krishna -- Thane, Thynn -- Scimone, Adam -- Thane, Nay -- Henke, Jessica -- Wang, Tom -- Ruppert, Jessica -- Shah, Neha -- Rotter, Kelsi -- Hodges, Jennifer -- Ingenthron, Elizabeth -- Cordes, Matt -- Kohlberg, Sara -- Sgro, Jennifer -- Delgado, Brandon -- Mead, Kelly -- Chinwalla, Asif -- Leonard, Shawn -- Crouse, Kevin -- Collura, Kristi -- Kudrna, Dave -- Currie, Jennifer -- He, Ruifeng -- Angelova, Angelina -- Rajasekar, Shanmugam -- Mueller, Teri -- Lomeli, Rene -- Scara, Gabriel -- Ko, Ara -- Delaney, Krista -- Wissotski, Marina -- Lopez, Georgina -- Campos, David -- Braidotti, Michele -- Ashley, Elizabeth -- Golser, Wolfgang -- Kim, HyeRan -- Lee, Seunghee -- Lin, Jinke -- Dujmic, Zeljko -- Kim, Woojin -- Talag, Jayson -- Zuccolo, Andrea -- Fan, Chuanzhu -- Sebastian, Aswathy -- Kramer, Melissa -- Spiegel, Lori -- Nascimento, Lidia -- Zutavern, Theresa -- Miller, Beth -- Ambroise, Claude -- Muller, Stephanie -- Spooner, Will -- Narechania, Apurva -- Ren, Liya -- Wei, Sharon -- Kumari, Sunita -- Faga, Ben -- Levy, Michael J -- McMahan, Linda -- Van Buren, Peter -- Vaughn, Matthew W -- Ying, Kai -- Yeh, Cheng-Ting -- Emrich, Scott J -- Jia, Yi -- Kalyanaraman, Ananth -- Hsia, An-Ping -- Barbazuk, W Brad -- Baucom, Regina S -- Brutnell, Thomas P -- Carpita, Nicholas C -- Chaparro, Cristian -- Chia, Jer-Ming -- Deragon, Jean-Marc -- Estill, James C -- Fu, Yan -- Jeddeloh, Jeffrey A -- Han, Yujun -- Lee, Hyeran -- Li, Pinghua -- Lisch, Damon R -- Liu, Sanzhen -- Liu, Zhijie -- Nagel, Dawn Holligan -- McCann, Maureen C -- SanMiguel, Phillip -- Myers, Alan M -- Nettleton, Dan -- Nguyen, John -- Penning, Bryan W -- Ponnala, Lalit -- Schneider, Kevin L -- Schwartz, David C -- Sharma, Anupma -- Soderlund, Carol -- Springer, Nathan M -- Sun, Qi -- Wang, Hao -- Waterman, Michael -- Westerman, Richard -- Wolfgruber, Thomas K -- Yang, Lixing -- Yu, Yeisoo -- Zhang, Lifang -- Zhou, Shiguo -- Zhu, Qihui -- Bennetzen, Jeffrey L -- Dawe, R Kelly -- Jiang, Jiming -- Jiang, Ning -- Presting, Gernot G -- Wessler, Susan R -- Aluru, Srinivas -- Martienssen, Robert A -- Clifton, Sandra W -- McCombie, W Richard -- Wing, Rod A -- Wilson, Richard K -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1112-5. doi: 10.1126/science.1178534.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Plant Genomics, Iowa State University, Ames, IA 50011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965430" target="_blank"〉PubMed〈/a〉

    The transcriptional landscape of the mammalian genome (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-09-06
    Description: This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carninci, P -- Kasukawa, T -- Katayama, S -- Gough, J -- Frith, M C -- Maeda, N -- Oyama, R -- Ravasi, T -- Lenhard, B -- Wells, C -- Kodzius, R -- Shimokawa, K -- Bajic, V B -- Brenner, S E -- Batalov, S -- Forrest, A R R -- Zavolan, M -- Davis, M J -- Wilming, L G -- Aidinis, V -- Allen, J E -- Ambesi-Impiombato, A -- Apweiler, R -- Aturaliya, R N -- Bailey, T L -- Bansal, M -- Baxter, L -- Beisel, K W -- Bersano, T -- Bono, H -- Chalk, A M -- Chiu, K P -- Choudhary, V -- Christoffels, A -- Clutterbuck, D R -- Crowe, M L -- Dalla, E -- Dalrymple, B P -- de Bono, B -- Della Gatta, G -- di Bernardo, D -- Down, T -- Engstrom, P -- Fagiolini, M -- Faulkner, G -- Fletcher, C F -- Fukushima, T -- Furuno, M -- Futaki, S -- Gariboldi, M -- Georgii-Hemming, P -- Gingeras, T R -- Gojobori, T -- Green, R E -- Gustincich, S -- Harbers, M -- Hayashi, Y -- Hensch, T K -- Hirokawa, N -- Hill, D -- Huminiecki, L -- Iacono, M -- Ikeo, K -- Iwama, A -- Ishikawa, T -- Jakt, M -- Kanapin, A -- Katoh, M -- Kawasawa, Y -- Kelso, J -- Kitamura, H -- Kitano, H -- Kollias, G -- Krishnan, S P T -- Kruger, A -- Kummerfeld, S K -- Kurochkin, I V -- Lareau, L F -- Lazarevic, D -- Lipovich, L -- Liu, J -- Liuni, S -- McWilliam, S -- Madan Babu, M -- Madera, M -- Marchionni, L -- Matsuda, H -- Matsuzawa, S -- Miki, H -- Mignone, F -- Miyake, S -- Morris, K -- Mottagui-Tabar, S -- Mulder, N -- Nakano, N -- Nakauchi, H -- Ng, P -- Nilsson, R -- Nishiguchi, S -- Nishikawa, S -- Nori, F -- Ohara, O -- Okazaki, Y -- Orlando, V -- Pang, K C -- Pavan, W J -- Pavesi, G -- Pesole, G -- Petrovsky, N -- Piazza, S -- Reed, J -- Reid, J F -- Ring, B Z -- Ringwald, M -- Rost, B -- Ruan, Y -- Salzberg, S L -- Sandelin, A -- Schneider, C -- Schonbach, C -- Sekiguchi, K -- Semple, C A M -- Seno, S -- Sessa, L -- Sheng, Y -- Shibata, Y -- Shimada, H -- Shimada, K -- Silva, D -- Sinclair, B -- Sperling, S -- Stupka, E -- Sugiura, K -- Sultana, R -- Takenaka, Y -- Taki, K -- Tammoja, K -- Tan, S L -- Tang, S -- Taylor, M S -- Tegner, J -- Teichmann, S A -- Ueda, H R -- van Nimwegen, E -- Verardo, R -- Wei, C L -- Yagi, K -- Yamanishi, H -- Zabarovsky, E -- Zhu, S -- Zimmer, A -- Hide, W -- Bult, C -- Grimmond, S M -- Teasdale, R D -- Liu, E T -- Brusic, V -- Quackenbush, J -- Wahlestedt, C -- Mattick, J S -- Hume, D A -- Kai, C -- Sasaki, D -- Tomaru, Y -- Fukuda, S -- Kanamori-Katayama, M -- Suzuki, M -- Aoki, J -- Arakawa, T -- Iida, J -- Imamura, K -- Itoh, M -- Kato, T -- Kawaji, H -- Kawagashira, N -- Kawashima, T -- Kojima, M -- Kondo, S -- Konno, H -- Nakano, K -- Ninomiya, N -- Nishio, T -- Okada, M -- Plessy, C -- Shibata, K -- Shiraki, T -- Suzuki, S -- Tagami, M -- Waki, K -- Watahiki, A -- Okamura-Oho, Y -- Suzuki, H -- Kawai, J -- Hayashizaki, Y -- FANTOM Consortium -- RIKEN Genome Exploration Research Group and Genome Science Group (Genome Network Project Core Group) -- TGM03P17/Telethon/Italy -- TGM06S01/Telethon/Italy -- New York, N.Y. -- Science. 2005 Sep 2;309(5740):1559-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16141072" target="_blank"〉PubMed〈/a〉

    Real-time DNA sequencing from single polymerase molecules (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-11-22
    Description: We present single-molecule, real-time sequencing data obtained from a DNA polymerase performing uninterrupted template-directed synthesis using four distinguishable fluorescently labeled deoxyribonucleoside triphosphates (dNTPs). We detected the temporal order of their enzymatic incorporation into a growing DNA strand with zero-mode waveguide nanostructure arrays, which provide optical observation volume confinement and enable parallel, simultaneous detection of thousands of single-molecule sequencing reactions. Conjugation of fluorophores to the terminal phosphate moiety of the dNTPs allows continuous observation of DNA synthesis over thousands of bases without steric hindrance. The data report directly on polymerase dynamics, revealing distinct polymerization states and pause sites corresponding to DNA secondary structure. Sequence data were aligned with the known reference sequence to assay biophysical parameters of polymerization for each template position. Consensus sequences were generated from the single-molecule reads at 15-fold coverage, showing a median accuracy of 99.3%, with no systematic error beyond fluorophore-dependent error rates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eid, John -- Fehr, Adrian -- Gray, Jeremy -- Luong, Khai -- Lyle, John -- Otto, Geoff -- Peluso, Paul -- Rank, David -- Baybayan, Primo -- Bettman, Brad -- Bibillo, Arkadiusz -- Bjornson, Keith -- Chaudhuri, Bidhan -- Christians, Frederick -- Cicero, Ronald -- Clark, Sonya -- Dalal, Ravindra -- Dewinter, Alex -- Dixon, John -- Foquet, Mathieu -- Gaertner, Alfred -- Hardenbol, Paul -- Heiner, Cheryl -- Hester, Kevin -- Holden, David -- Kearns, Gregory -- Kong, Xiangxu -- Kuse, Ronald -- Lacroix, Yves -- Lin, Steven -- Lundquist, Paul -- Ma, Congcong -- Marks, Patrick -- Maxham, Mark -- Murphy, Devon -- Park, Insil -- Pham, Thang -- Phillips, Michael -- Roy, Joy -- Sebra, Robert -- Shen, Gene -- Sorenson, Jon -- Tomaney, Austin -- Travers, Kevin -- Trulson, Mark -- Vieceli, John -- Wegener, Jeffrey -- Wu, Dawn -- Yang, Alicia -- Zaccarin, Denis -- Zhao, Peter -- Zhong, Frank -- Korlach, Jonas -- Turner, Stephen -- R01HG003710/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 2;323(5910):133-8. doi: 10.1126/science.1162986.

    Structural basis of transcription: backtracked RNA polymerase II at 3.4 angstrom resolution (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-30
    Description: Transcribing RNA polymerases oscillate between three stable states, two of which, pre- and posttranslocated, were previously subjected to x-ray crystal structure determination. We report here the crystal structure of RNA polymerase II in the third state, the reverse translocated, or "backtracked" state. The defining feature of the backtracked structure is a binding site for the first backtracked nucleotide. This binding site is occupied in case of nucleotide misincorporation in the RNA or damage to the DNA, and is termed the "P" site because it supports proofreading. The predominant mechanism of proofreading is the excision of a dinucleotide in the presence of the elongation factor SII (TFIIS). Structure determination of a cocrystal with TFIIS reveals a rearrangement whereby cleavage of the RNA may take place.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2718261/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2718261/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Dong -- Bushnell, David A -- Huang, Xuhui -- Westover, Kenneth D -- Levitt, Michael -- Kornberg, Roger D -- GM036559/GM/NIGMS NIH HHS/ -- GM041455/GM/NIGMS NIH HHS/ -- GM049985/GM/NIGMS NIH HHS/ -- K99 GM085136/GM/NIGMS NIH HHS/ -- K99 GM085136-01/GM/NIGMS NIH HHS/ -- R00 GM085136/GM/NIGMS NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM041455/GM/NIGMS NIH HHS/ -- R01 GM049985/GM/NIGMS NIH HHS/ -- R01 GM049985-16/GM/NIGMS NIH HHS/ -- R37 GM036659/GM/NIGMS NIH HHS/ -- R37 GM036659-22/GM/NIGMS NIH HHS/ -- R37 GM041455/GM/NIGMS NIH HHS/ -- R37 GM041455-20/GM/NIGMS NIH HHS/ -- U54 GM072970/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 29;324(5931):1203-6. doi: 10.1126/science.1168729.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19478184" target="_blank"〉PubMed〈/a〉

    Solution nuclear magnetic resonance structure of membrane-integral diacylglycerol kinase (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-06-27
    Description: Escherichia coli diacylglycerol kinase (DAGK) represents a family of integral membrane enzymes that is unrelated to all other phosphotransferases. We have determined the three-dimensional structure of the DAGK homotrimer with the use of solution nuclear magnetic resonance. The third transmembrane helix from each subunit is domain-swapped with the first and second transmembrane segments from an adjacent subunit. Each of DAGK's three active sites resembles a portico. The cornice of the portico appears to be the determinant of DAGK's lipid substrate specificity and overhangs the site of phosphoryl transfer near the water-membrane interface. Mutations to cysteine that caused severe misfolding were located in or near the active site, indicating a high degree of overlap between sites responsible for folding and for catalysis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2764269/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2764269/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Horn, Wade D -- Kim, Hak-Jun -- Ellis, Charles D -- Hadziselimovic, Arina -- Sulistijo, Endah S -- Karra, Murthy D -- Tian, Changlin -- Sonnichsen, Frank D -- Sanders, Charles R -- R01 GM047485/GM/NIGMS NIH HHS/ -- R01 GM047485-17/GM/NIGMS NIH HHS/ -- R01 GM47485/GM/NIGMS NIH HHS/ -- T32 NS007491/NS/NINDS NIH HHS/ -- T32 NS007491-09/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1726-9. doi: 10.1126/science.1171716.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Center for Structural Biology, Vanderbilt University, Nashville, TN 37232, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19556511" target="_blank"〉PubMed〈/a〉

    Structural basis of immune evasion at the site of CD4 attachment on HIV-1 gp120 (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: The site on HIV-1 gp120 that binds to the CD4 receptor is vulnerable to antibodies. However, most antibodies that interact with this site cannot neutralize HIV-1. To understand the basis of this resistance, we determined co-crystal structures for two poorly neutralizing, CD4-binding site (CD4BS) antibodies, F105 and b13, in complexes with gp120. Both antibodies exhibited approach angles to gp120 similar to those of CD4 and a rare, broadly neutralizing CD4BS antibody, b12. Slight differences in recognition, however, resulted in substantial differences in F105- and b13-bound conformations relative to b12-bound gp120. Modeling and binding experiments revealed these conformations to be poorly compatible with the viral spike. This incompatibility, the consequence of slight differences in CD4BS recognition, renders HIV-1 resistant to all but the most accurately targeted antibodies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2862588/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2862588/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Lei -- Kwon, Young Do -- Zhou, Tongqing -- Wu, Xueling -- O'Dell, Sijy -- Cavacini, Lisa -- Hessell, Ann J -- Pancera, Marie -- Tang, Min -- Xu, Ling -- Yang, Zhi-Yong -- Zhang, Mei-Yun -- Arthos, James -- Burton, Dennis R -- Dimitrov, Dimiter S -- Nabel, Gary J -- Posner, Marshall R -- Sodroski, Joseph -- Wyatt, Richard -- Mascola, John R -- Kwong, Peter D -- Z99 AI999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1123-7. doi: 10.1126/science.1175868.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vaccine Research Center, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965434" target="_blank"〉PubMed〈/a〉

    Kemp elimination catalysts by computational enzyme design (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-03-21
    Description: The design of new enzymes for reactions not catalysed by naturally occurring biocatalysts is a challenge for protein engineering and is a critical test of our understanding of enzyme catalysis. Here we describe the computational design of eight enzymes that use two different catalytic motifs to catalyse the Kemp elimination-a model reaction for proton transfer from carbon-with measured rate enhancements of up to 10(5) and multiple turnovers. Mutational analysis confirms that catalysis depends on the computationally designed active sites, and a high-resolution crystal structure suggests that the designs have close to atomic accuracy. Application of in vitro evolution to enhance the computational designs produced a 〉200-fold increase in k(cat)/K(m) (k(cat)/K(m) of 2,600 M(-1)s(-1) and k(cat)/k(uncat) of 〉10(6)). These results demonstrate the power of combining computational protein design with directed evolution for creating new enzymes, and we anticipate the creation of a wide range of useful new catalysts in the future.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rothlisberger, Daniela -- Khersonsky, Olga -- Wollacott, Andrew M -- Jiang, Lin -- DeChancie, Jason -- Betker, Jamie -- Gallaher, Jasmine L -- Althoff, Eric A -- Zanghellini, Alexandre -- Dym, Orly -- Albeck, Shira -- Houk, Kendall N -- Tawfik, Dan S -- Baker, David -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 May 8;453(7192):190-5. doi: 10.1038/nature06879.

    Cancer-associated IDH1 mutations produce 2-hydroxyglutarate (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-26
    Description: Mutations in the enzyme cytosolic isocitrate dehydrogenase 1 (IDH1) are a common feature of a major subset of primary human brain cancers. These mutations occur at a single amino acid residue of the IDH1 active site, resulting in loss of the enzyme's ability to catalyse conversion of isocitrate to alpha-ketoglutarate. However, only a single copy of the gene is mutated in tumours, raising the possibility that the mutations do not result in a simple loss of function. Here we show that cancer-associated IDH1 mutations result in a new ability of the enzyme to catalyse the NADPH-dependent reduction of alpha-ketoglutarate to R(-)-2-hydroxyglutarate (2HG). Structural studies demonstrate that when arginine 132 is mutated to histidine, residues in the active site are shifted to produce structural changes consistent with reduced oxidative decarboxylation of isocitrate and acquisition of the ability to convert alpha-ketoglutarate to 2HG. Excess accumulation of 2HG has been shown to lead to an elevated risk of malignant brain tumours in patients with inborn errors of 2HG metabolism. Similarly, in human malignant gliomas harbouring IDH1 mutations, we find markedly elevated levels of 2HG. These data demonstrate that the IDH1 mutations result in production of the onco-metabolite 2HG, and indicate that the excess 2HG which accumulates in vivo contributes to the formation and malignant progression of gliomas.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818760/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dang, Lenny -- White, David W -- Gross, Stefan -- Bennett, Bryson D -- Bittinger, Mark A -- Driggers, Edward M -- Fantin, Valeria R -- Jang, Hyun Gyung -- Jin, Shengfang -- Keenan, Marie C -- Marks, Kevin M -- Prins, Robert M -- Ward, Patrick S -- Yen, Katharine E -- Liau, Linda M -- Rabinowitz, Joshua D -- Cantley, Lewis C -- Thompson, Craig B -- Vander Heiden, Matthew G -- Su, Shinsan M -- P01 CA104838/CA/NCI NIH HHS/ -- P01 CA104838-05/CA/NCI NIH HHS/ -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 CA105463/CA/NCI NIH HHS/ -- R01 CA105463-06/CA/NCI NIH HHS/ -- R21 CA128620/CA/NCI NIH HHS/ -- England -- Nature. 2009 Dec 10;462(7274):739-44. doi: 10.1038/nature08617.

    Structure and hydration of membranes embedded with voltage-sensing domains (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-27
    Description: Despite the growing number of atomic-resolution membrane protein structures, direct structural information about proteins in their native membrane environment is scarce. This problem is particularly relevant in the case of the highly charged S1-S4 voltage-sensing domains responsible for nerve impulses, where interactions with the lipid bilayer are critical for the function of voltage-activated ion channels. Here we use neutron diffraction, solid-state nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics simulations to investigate the structure and hydration of bilayer membranes containing S1-S4 voltage-sensing domains. Our results show that voltage sensors adopt transmembrane orientations and cause a modest reshaping of the surrounding lipid bilayer, and that water molecules intimately interact with the protein within the membrane. These structural findings indicate that voltage sensors have evolved to interact with the lipid membrane while keeping energetic and structural perturbations to a minimum, and that water penetrates the membrane, to hydrate charged residues and shape the transmembrane electric field.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2784928/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2784928/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krepkiy, Dmitriy -- Mihailescu, Mihaela -- Freites, J Alfredo -- Schow, Eric V -- Worcester, David L -- Gawrisch, Klaus -- Tobias, Douglas J -- White, Stephen H -- Swartz, Kenton J -- GM74737/GM/NIGMS NIH HHS/ -- GM86685/GM/NIGMS NIH HHS/ -- P01 GM086685/GM/NIGMS NIH HHS/ -- R01 GM074637/GM/NIGMS NIH HHS/ -- R01 RR014812/RR/NCRR NIH HHS/ -- ZIA NS002945-13/Intramural NIH HHS/ -- England -- Nature. 2009 Nov 26;462(7272):473-9. doi: 10.1038/nature08542.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Physiology and Biophysics Section, Porter Neuroscience Research Center, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, Maryland 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19940918" target="_blank"〉PubMed〈/a〉
