Beschreibung: Infectious and inflammatory diseases have repeatedly shown strong genetic associations within the major histocompatibility complex (MHC); however, the basis for these associations remains elusive. To define host genetic effects on the outcome of a chronic viral infection, we performed genome-wide association analysis in a multiethnic cohort of HIV-1 controllers and progressors, and we analyzed the effects of individual amino acids within the classical human leukocyte antigen (HLA) proteins. We identified 〉300 genome-wide significant single-nucleotide polymorphisms (SNPs) within the MHC and none elsewhere. Specific amino acids in the HLA-B peptide binding groove, as well as an independent HLA-C effect, explain the SNP associations and reconcile both protective and risk HLA alleles. These results implicate the nature of the HLA-viral peptide interaction as the major factor modulating durable control of HIV infection.〈br /〉〈br /〉〈a

Beschreibung: Decreased cardiac contractility is a central feature of systolic heart failure. Existing drugs increase cardiac contractility indirectly through signaling cascades but are limited by their mechanism-related adverse effects. To avoid these limitations, we previously developed omecamtiv mecarbil, a small-molecule, direct activator of cardiac myosin. Here, we show that it binds to the myosin catalytic domain and operates by an allosteric mechanism to increase the transition rate of myosin into the strongly actin-bound force-generating state. Paradoxically, it inhibits adenosine 5'-triphosphate turnover in the absence of actin, which suggests that it stabilizes an actin-bound conformation of myosin. In animal models, omecamtiv mecarbil increases cardiac function by increasing the duration of ejection without changing the rates of contraction. Cardiac myosin activation may provide a new therapeutic approach for systolic heart failure.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4090309/" 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/PMC4090309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malik, Fady I -- Hartman, James J -- Elias, Kathleen A -- Morgan, Bradley P -- Rodriguez, Hector -- Brejc, Katjusa -- Anderson, Robert L -- Sueoka, Sandra H -- Lee, Kenneth H -- Finer, Jeffrey T -- Sakowicz, Roman -- Baliga, Ramesh -- Cox, David R -- Garard, Marc -- Godinez, Guillermo -- Kawas, Raja -- Kraynack, Erica -- Lenzi, David -- Lu, Pu Ping -- Muci, Alexander -- Niu, Congrong -- Qian, Xiangping -- Pierce, Daniel W -- Pokrovskii, Maria -- Suehiro, Ion -- Sylvester, Sheila -- Tochimoto, Todd -- Valdez, Corey -- Wang, Wenyue -- Katori, Tatsuo -- Kass, David A -- Shen, You-Tang -- Vatner, Stephen F -- Morgans, David J -- 1-R43-HL-66647-1/HL/NHLBI NIH HHS/ -- R01 HL106511/HL/NHLBI NIH HHS/ -- R43 HL066647/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 18;331(6023):1439-43. doi: 10.1126/science.1200113.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Preclinical Research and Development, Cytokinetics, Inc., South San Francisco, CA 94080, USA. fmalik@cytokinetics.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21415352" target="_blank"〉PubMed〈/a〉

Beschreibung: Passive transfer of broadly neutralizing HIV antibodies can prevent infection, which suggests that vaccines that elicit such antibodies would be protective. Thus far, however, few broadly neutralizing HIV antibodies that occur naturally have been characterized. To determine whether these antibodies are part of a larger group of related molecules, we cloned 576 new HIV antibodies from four unrelated individuals. All four individuals produced expanded clones of potent broadly neutralizing CD4-binding-site antibodies that mimic binding to CD4. Despite extensive hypermutation, the new antibodies shared a consensus sequence of 68 immunoglobulin H (IgH) chain amino acids and arise independently from two related IgH genes. Comparison of the crystal structure of one of the antibodies to the broadly neutralizing antibody VRC01 revealed conservation of the contacts to the HIV spike.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3351836/" 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/PMC3351836/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheid, Johannes F -- Mouquet, Hugo -- Ueberheide, Beatrix -- Diskin, Ron -- Klein, Florian -- Oliveira, Thiago Y K -- Pietzsch, John -- Fenyo, David -- Abadir, Alexander -- Velinzon, Klara -- Hurley, Arlene -- Myung, Sunnie -- Boulad, Farid -- Poignard, Pascal -- Burton, Dennis R -- Pereyra, Florencia -- Ho, David D -- Walker, Bruce D -- Seaman, Michael S -- Bjorkman, Pamela J -- Chait, Brian T -- Nussenzweig, Michel C -- P01 AI081677/AI/NIAID NIH HHS/ -- P30 AI060354/AI/NIAID NIH HHS/ -- R01 AI033292/AI/NIAID NIH HHS/ -- RR00862/RR/NCRR NIH HHS/ -- RR022220/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Sep 16;333(6049):1633-7. doi: 10.1126/science.1207227.

Beschreibung: Intense femtosecond x-ray pulses produced at the Linac Coherent Light Source (LCLS) were used for simultaneous x-ray diffraction (XRD) and x-ray emission spectroscopy (XES) of microcrystals of photosystem II (PS II) at room temperature. This method probes the overall protein structure and the electronic structure of the Mn4CaO5 cluster in the oxygen-evolving complex of PS II. XRD data are presented from both the dark state (S1) and the first illuminated state (S2) of PS II. Our simultaneous XRD-XES study shows that the PS II crystals are intact during our measurements at the LCLS, not only with respect to the structure of PS II, but also with regard to the electronic structure of the highly radiation-sensitive Mn4CaO5 cluster, opening new directions for future dynamics studies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3732582/" 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/PMC3732582/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kern, Jan -- Alonso-Mori, Roberto -- Tran, Rosalie -- Hattne, Johan -- Gildea, Richard J -- Echols, Nathaniel -- Glockner, Carina -- Hellmich, Julia -- Laksmono, Hartawan -- Sierra, Raymond G -- Lassalle-Kaiser, Benedikt -- Koroidov, Sergey -- Lampe, Alyssa -- Han, Guangye -- Gul, Sheraz -- Difiore, Dorte -- Milathianaki, Despina -- Fry, Alan R -- Miahnahri, Alan -- Schafer, Donald W -- Messerschmidt, Marc -- Seibert, M Marvin -- Koglin, Jason E -- Sokaras, Dimosthenis -- Weng, Tsu-Chien -- Sellberg, Jonas -- Latimer, Matthew J -- Grosse-Kunstleve, Ralf W -- Zwart, Petrus H -- White, William E -- Glatzel, Pieter -- Adams, Paul D -- Bogan, Michael J -- Williams, Garth J -- Boutet, Sebastien -- Messinger, Johannes -- Zouni, Athina -- Sauter, Nicholas K -- Yachandra, Vittal K -- Bergmann, Uwe -- Yano, Junko -- GM095887/GM/NIGMS NIH HHS/ -- GM102520/GM/NIGMS NIH HHS/ -- P01 GM063210/GM/NIGMS NIH HHS/ -- P41GM103393/GM/NIGMS NIH HHS/ -- R01 GM055302/GM/NIGMS NIH HHS/ -- R01 GM095887/GM/NIGMS NIH HHS/ -- R01 GM102520/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Apr 26;340(6131):491-5. doi: 10.1126/science.1234273.

Beschreibung: X-ray crystallography of G protein-coupled receptors and other membrane proteins is hampered by difficulties associated with growing sufficiently large crystals that withstand radiation damage and yield high-resolution data at synchrotron sources. We used an x-ray free-electron laser (XFEL) with individual 50-femtosecond-duration x-ray pulses to minimize radiation damage and obtained a high-resolution room-temperature structure of a human serotonin receptor using sub-10-micrometer microcrystals grown in a membrane mimetic matrix known as lipidic cubic phase. Compared with the structure solved by using traditional microcrystallography from cryo-cooled crystals of about two orders of magnitude larger volume, the room-temperature XFEL structure displays a distinct distribution of thermal motions and conformations of residues that likely more accurately represent the receptor structure and dynamics in a cellular environment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3902108/" 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/PMC3902108/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Wei -- Wacker, Daniel -- Gati, Cornelius -- Han, Gye Won -- James, Daniel -- Wang, Dingjie -- Nelson, Garrett -- Weierstall, Uwe -- Katritch, Vsevolod -- Barty, Anton -- Zatsepin, Nadia A -- Li, Dianfan -- Messerschmidt, Marc -- Boutet, Sebastien -- Williams, Garth J -- Koglin, Jason E -- Seibert, M Marvin -- Wang, Chong -- Shah, Syed T A -- Basu, Shibom -- Fromme, Raimund -- Kupitz, Christopher -- Rendek, Kimberley N -- Grotjohann, Ingo -- Fromme, Petra -- Kirian, Richard A -- Beyerlein, Kenneth R -- White, Thomas A -- Chapman, Henry N -- Caffrey, Martin -- Spence, John C H -- Stevens, Raymond C -- Cherezov, Vadim -- P50 GM073197/GM/NIGMS NIH HHS/ -- P50 GM073210/GM/NIGMS NIH HHS/ -- R01 GM095583/GM/NIGMS NIH HHS/ -- U54 GM094599/GM/NIGMS NIH HHS/ -- U54 GM094618/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Dec 20;342(6165):1521-4. doi: 10.1126/science.1244142.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Structural and Computational Biology, The Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24357322" target="_blank"〉PubMed〈/a〉

Beschreibung: The Trypanosoma brucei cysteine protease cathepsin B (TbCatB), which is involved in host protein degradation, is a promising target to develop new treatments against sleeping sickness, a fatal disease caused by this protozoan parasite. The structure of the mature, active form of TbCatB has so far not provided sufficient information for the design of a safe and specific drug against T. brucei. By combining two recent innovations, in vivo crystallization and serial femtosecond crystallography, we obtained the room-temperature 2.1 angstrom resolution structure of the fully glycosylated precursor complex of TbCatB. The structure reveals the mechanism of native TbCatB inhibition and demonstrates that new biomolecular information can be obtained by the "diffraction-before-destruction" approach of x-ray free-electron lasers from hundreds of thousands of individual microcrystals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3786669/" 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/PMC3786669/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Redecke, Lars -- Nass, Karol -- DePonte, Daniel P -- White, Thomas A -- Rehders, Dirk -- Barty, Anton -- Stellato, Francesco -- Liang, Mengning -- Barends, Thomas R M -- Boutet, Sebastien -- Williams, Garth J -- Messerschmidt, Marc -- Seibert, M Marvin -- Aquila, Andrew -- Arnlund, David -- Bajt, Sasa -- Barth, Torsten -- Bogan, Michael J -- Caleman, Carl -- Chao, Tzu-Chiao -- Doak, R Bruce -- Fleckenstein, Holger -- Frank, Matthias -- Fromme, Raimund -- Galli, Lorenzo -- Grotjohann, Ingo -- Hunter, Mark S -- Johansson, Linda C -- Kassemeyer, Stephan -- Katona, Gergely -- Kirian, Richard A -- Koopmann, Rudolf -- Kupitz, Chris -- Lomb, Lukas -- Martin, Andrew V -- Mogk, Stefan -- Neutze, Richard -- Shoeman, Robert L -- Steinbrener, Jan -- Timneanu, Nicusor -- Wang, Dingjie -- Weierstall, Uwe -- Zatsepin, Nadia A -- Spence, John C H -- Fromme, Petra -- Schlichting, Ilme -- Duszenko, Michael -- Betzel, Christian -- Chapman, Henry N -- 1R01GM095583/GM/NIGMS NIH HHS/ -- R01 GM095583/GM/NIGMS NIH HHS/ -- U54 GM094599/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 11;339(6116):227-30. doi: 10.1126/science.1229663.

Beschreibung: Serial femtosecond crystallography using ultrashort pulses from x-ray free electron lasers (XFELs) enables studies of the light-triggered dynamics of biomolecules. We used microcrystals of photoactive yellow protein (a bacterial blue light photoreceptor) as a model system and obtained high-resolution, time-resolved difference electron density maps of excellent quality with strong features; these allowed the determination of structures of reaction intermediates to a resolution of 1.6 angstroms. Our results open the way to the study of reversible and nonreversible biological reactions on time scales as short as femtoseconds under conditions that maximize the extent of reaction initiation throughout the crystal.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4361027/" 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/PMC4361027/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tenboer, Jason -- Basu, Shibom -- Zatsepin, Nadia -- Pande, Kanupriya -- Milathianaki, Despina -- Frank, Matthias -- Hunter, Mark -- Boutet, Sebastien -- Williams, Garth J -- Koglin, Jason E -- Oberthuer, Dominik -- Heymann, Michael -- Kupitz, Christopher -- Conrad, Chelsie -- Coe, Jesse -- Roy-Chowdhury, Shatabdi -- Weierstall, Uwe -- James, Daniel -- Wang, Dingjie -- Grant, Thomas -- Barty, Anton -- Yefanov, Oleksandr -- Scales, Jennifer -- Gati, Cornelius -- Seuring, Carolin -- Srajer, Vukica -- Henning, Robert -- Schwander, Peter -- Fromme, Raimund -- Ourmazd, Abbas -- Moffat, Keith -- Van Thor, Jasper J -- Spence, John C H -- Fromme, Petra -- Chapman, Henry N -- Schmidt, Marius -- P41 GM103543/GM/NIGMS NIH HHS/ -- R01GM095583/GM/NIGMS NIH HHS/ -- R24 GM111072/GM/NIGMS NIH HHS/ -- R24GM111072/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1242-6. doi: 10.1126/science.1259357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physics Department, University of Wisconsin, Milwaukee, WI 53211, USA. ; Department of Chemistry and Biochemistry, Arizona State University, Tempe, AZ 85287, USA. ; Department of Physics, Arizona State University, Tempe, AZ 85287, USA. ; Linac Coherent Light Source, SLAC National Accelerator Laboratory, Sand Hill Road, Menlo Park, CA 94025, USA. ; Lawrence Livermore National Laboratory, Livermore, CA 94550, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany. ; Center for Free Electron Laser Science, Deutsches Elektronen Synchrotron DESY, Notkestrasse 85, 22607 Hamburg, Germany. ; Hauptman-Woodward Institute, State University of New York at Buffalo, 700 Ellicott Street, Buffalo, NY 14203, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany.

Beschreibung: The initiation of transcription by RNA polymerase II is a multistage process. X-ray crystal structures of transcription complexes containing short RNAs reveal three structural states: one with 2- and 3-nucleotide RNAs, in which only the 3'-end of the RNA is detectable; a second state with 4- and 5-nucleotide RNAs, with an RNA-DNA hybrid in a grossly distorted conformation; and a third state with RNAs of 6 nucleotides and longer, essentially the same as a stable elongating complex. The transition from the first to the second state correlates with a markedly reduced frequency of abortive initiation. The transition from the second to the third state correlates with partial "bubble collapse" and promoter escape. Polymerase structure is permissive for abortive initiation, thereby setting a lower limit on polymerase-promoter complex lifetime and allowing the dissociation of nonspecific complexes. Abortive initiation may be viewed as promoter proofreading, and the structural transitions as checkpoints for promoter control.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3179255/" 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/PMC3179255/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Xin -- Bushnell, David A -- Silva, Daniel-Adriano -- Huang, Xuhui -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM049985/GM/NIGMS NIH HHS/ -- R01 AI021144/AI/NIAID NIH HHS/ -- R01 AI021144-27/AI/NIAID NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM049985/GM/NIGMS NIH HHS/ -- R01 GM049985-19/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Jul 29;333(6042):633-7. doi: 10.1126/science.1206629.〈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/21798951" target="_blank"〉PubMed〈/a〉

Beschreibung: Oxamniquine resistance evolved in the human blood fluke (Schistosoma mansoni) in Brazil in the 1970s. We crossed parental parasites differing ~500-fold in drug response, determined drug sensitivity and marker segregation in clonally derived second-generation progeny, and identified a single quantitative trait locus (logarithm of odds = 31) on chromosome 6. A sulfotransferase was identified as the causative gene by using RNA interference knockdown and biochemical complementation assays, and we subsequently demonstrated independent origins of loss-of-function mutations in field-derived and laboratory-selected resistant parasites. These results demonstrate the utility of linkage mapping in a human helminth parasite, while crystallographic analyses of protein-drug interactions illuminate the mode of drug action and provide a framework for rational design of oxamniquine derivatives that kill both S. mansoni and S. haematobium, the two species responsible for 〉99% of schistosomiasis cases worldwide.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136436/" 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/PMC4136436/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Valentim, Claudia L L -- Cioli, Donato -- Chevalier, Frederic D -- Cao, Xiaohang -- Taylor, Alexander B -- Holloway, Stephen P -- Pica-Mattoccia, Livia -- Guidi, Alessandra -- Basso, Annalisa -- Tsai, Isheng J -- Berriman, Matthew -- Carvalho-Queiroz, Claudia -- Almeida, Marcio -- Aguilar, Hector -- Frantz, Doug E -- Hart, P John -- LoVerde, Philip T -- Anderson, Timothy J C -- 098051/Wellcome Trust/United Kingdom -- 5R21-AI072704/AI/NIAID NIH HHS/ -- 5R21-AI096277/AI/NIAID NIH HHS/ -- C06 RR013556/RR/NCRR NIH HHS/ -- HHSN272201000005I/PHS HHS/ -- R01 AI097576/AI/NIAID NIH HHS/ -- R01-AI097576/AI/NIAID NIH HHS/ -- R21 AI072704/AI/NIAID NIH HHS/ -- R21 AI096277/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Dec 13;342(6164):1385-9. doi: 10.1126/science.1243106.

Beschreibung: The protein density and arrangement of subunits of a complete, 32-protein, RNA polymerase II (pol II) transcription pre-initiation complex (PIC) were determined by means of cryogenic electron microscopy and a combination of chemical cross-linking and mass spectrometry. The PIC showed a marked division in two parts, one containing all the general transcription factors (GTFs) and the other pol II. Promoter DNA was associated only with the GTFs, suspended above the pol II cleft and not in contact with pol II. This structural principle of the PIC underlies its conversion to a transcriptionally active state; the PIC is poised for the formation of a transcription bubble and descent of the DNA into the pol II cleft.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4039082/" 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/PMC4039082/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Murakami, Kenji -- Elmlund, Hans -- Kalisman, Nir -- Bushnell, David A -- Adams, Christopher M -- Azubel, Maia -- Elmlund, Dominika -- Levi-Kalisman, Yael -- Liu, Xin -- Gibbons, Brian J -- Levitt, Michael -- Kornberg, Roger D -- AI21144/AI/NIAID NIH HHS/ -- GM063817/GM/NIGMS NIH HHS/ -- GM49885/GM/NIGMS NIH HHS/ -- R01 AI021144/AI/NIAID NIH HHS/ -- R01 GM036659/GM/NIGMS NIH HHS/ -- R01 GM063817/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 8;342(6159):1238724. doi: 10.1126/science.1238724.
