    Description: Glycosyltransferases (GTs), an essential class of ubiquitous enzymes, are generally perceived as unidirectional catalysts. In contrast, we report that four glycosyltransferases from two distinct natural product biosynthetic pathways-calicheamicin and vancomycin-readily catalyze reversible reactions, allowing sugars and aglycons to be exchanged with ease. As proof of the broader applicability of these new reactions, more than 70 differentially glycosylated calicheamicin and vancomycin variants are reported. This study suggests the reversibility of GT-catalyzed reactions may be general and useful for generating exotic nucleotide sugars, establishing in vitro GT activity in complex systems, and enhancing natural product diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Changsheng -- Griffith, Byron R -- Fu, Qiang -- Albermann, Christoph -- Fu, Xun -- Lee, In-Kyoung -- Li, Lingjun -- Thorson, Jon S -- AI52218/AI/NIAID NIH HHS/ -- CA84374/CA/NCI NIH HHS/ -- GM70637/GM/NIGMS NIH HHS/ -- U19 CA113297/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Sep 1;313(5791):1291-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Biosynthetic Chemistry, Pharmaceutical Sciences Division, School of Pharmacy, National Cooperative Drug Discovery Group Program, University of Wisconsin (UW)-Madison, 777 Highland Avenue, Madison, WI 53705-2222, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16946071" target="_blank"〉PubMed〈/a〉

    Description: The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used to develop probes to interrogate 37,470 single-nucleotide polymorphisms (SNPs) in 497 cattle from 19 geographically and biologically diverse breeds. These data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Domestication and artificial selection appear to have left detectable signatures of selection within the cattle genome, yet the current levels of diversity within breeds are at least as great as exists within humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" 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/PMC2735092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bovine HapMap Consortium -- Gibbs, Richard A -- Taylor, Jeremy F -- Van Tassell, Curtis P -- Barendse, William -- Eversole, Kellye A -- Gill, Clare A -- Green, Ronnie D -- Hamernik, Debora L -- Kappes, Steven M -- Lien, Sigbjorn -- Matukumalli, Lakshmi K -- McEwan, John C -- Nazareth, Lynne V -- Schnabel, Robert D -- Weinstock, George M -- Wheeler, David A -- Ajmone-Marsan, Paolo -- Boettcher, Paul J -- Caetano, Alexandre R -- Garcia, Jose Fernando -- Hanotte, Olivier -- Mariani, Paola -- Skow, Loren C -- Sonstegard, Tad S -- Williams, John L -- Diallo, Boubacar -- Hailemariam, Lemecha -- Martinez, Mario L -- Morris, Chris A -- Silva, Luiz O C -- Spelman, Richard J -- Mulatu, Woudyalew -- Zhao, Keyan -- Abbey, Colette A -- Agaba, Morris -- Araujo, Flabio R -- Bunch, Rowan J -- Burton, James -- Gorni, Chiara -- Olivier, Hanotte -- Harrison, Blair E -- Luff, Bill -- Machado, Marco A -- Mwakaya, Joel -- Plastow, Graham -- Sim, Warren -- Smith, Timothy -- Thomas, Merle B -- Valentini, Alessio -- Williams, Paul -- Womack, James -- Woolliams, John A -- Liu, Yue -- Qin, Xiang -- Worley, Kim C -- Gao, Chuan -- Jiang, Huaiyang -- Moore, Stephen S -- Ren, Yanru -- Song, Xing-Zhi -- Bustamante, Carlos D -- Hernandez, Ryan D -- Muzny, Donna M -- Patil, Shobha -- San Lucas, Anthony -- Fu, Qing -- Kent, Matthew P -- Vega, Richard -- Matukumalli, Aruna -- McWilliam, Sean -- Sclep, Gert -- Bryc, Katarzyna -- Choi, Jungwoo -- Gao, Hong -- Grefenstette, John J -- Murdoch, Brenda -- Stella, Alessandra -- Villa-Angulo, Rafael -- Wright, Mark -- Aerts, Jan -- Jann, Oliver -- Negrini, Riccardo -- Goddard, Mike E -- Hayes, Ben J -- Bradley, Daniel G -- Barbosa da Silva, Marcos -- Lau, Lilian P L -- Liu, George E -- Lynn, David J -- Panzitta, Francesca -- Dodds, Ken G -- R01 GM083606/GM/NIGMS NIH HHS/ -- R01 GM083606-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):528-32. doi: 10.1126/science.1167936.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390050" target="_blank"〉PubMed〈/a〉

    Description: We present a DNA library preparation method that has allowed us to reconstruct a high-coverage (30x) genome sequence of a Denisovan, an extinct relative of Neandertals. The quality of this genome allows a direct estimation of Denisovan heterozygosity indicating that genetic diversity in these archaic hominins was extremely low. It also allows tentative dating of the specimen on the basis of "missing evolution" in its genome, detailed measurements of Denisovan and Neandertal admixture into present-day human populations, and the generation of a near-complete catalog of genetic changes that swept to high frequency in modern humans since their divergence from Denisovans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3617501/" 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/PMC3617501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Matthias -- Kircher, Martin -- Gansauge, Marie-Theres -- Li, Heng -- Racimo, Fernando -- Mallick, Swapan -- Schraiber, Joshua G -- Jay, Flora -- Prufer, Kay -- de Filippo, Cesare -- Sudmant, Peter H -- Alkan, Can -- Fu, Qiaomei -- Do, Ron -- Rohland, Nadin -- Tandon, Arti -- Siebauer, Michael -- Green, Richard E -- Bryc, Katarzyna -- Briggs, Adrian W -- Stenzel, Udo -- Dabney, Jesse -- Shendure, Jay -- Kitzman, Jacob -- Hammer, Michael F -- Shunkov, Michael V -- Derevianko, Anatoli P -- Patterson, Nick -- Andres, Aida M -- Eichler, Evan E -- Slatkin, Montgomery -- Reich, David -- Kelso, Janet -- Paabo, Svante -- GM100233/GM/NIGMS NIH HHS/ -- R01 GM040282/GM/NIGMS NIH HHS/ -- R01 GM100233/GM/NIGMS NIH HHS/ -- R01-GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Oct 12;338(6104):222-6. doi: 10.1126/science.1224344.

    Description: We present the high-quality genome sequence of a approximately 45,000-year-old modern human male from Siberia. This individual derives from a population that lived before-or simultaneously with-the separation of the populations in western and eastern Eurasia and carries a similar amount of Neanderthal ancestry as present-day Eurasians. However, the genomic segments of Neanderthal ancestry are substantially longer than those observed in present-day individuals, indicating that Neanderthal gene flow into the ancestors of this individual occurred 7,000-13,000 years before he lived. We estimate an autosomal mutation rate of 0.4 x 10(-9) to 0.6 x 10(-9) per site per year, a Y chromosomal mutation rate of 0.7 x 10(-9) to 0.9 x 10(-9) per site per year based on the additional substitutions that have occurred in present-day non-Africans compared to this genome, and a mitochondrial mutation rate of 1.8 x 10(-8) to 3.2 x 10(-8) per site per year based on the age of the bone.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4753769/" 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/PMC4753769/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fu, Qiaomei -- Li, Heng -- Moorjani, Priya -- Jay, Flora -- Slepchenko, Sergey M -- Bondarev, Aleksei A -- Johnson, Philip L F -- Aximu-Petri, Ayinuer -- Prufer, Kay -- de Filippo, Cesare -- Meyer, Matthias -- Zwyns, Nicolas -- Salazar-Garcia, Domingo C -- Kuzmin, Yaroslav V -- Keates, Susan G -- Kosintsev, Pavel A -- Razhev, Dmitry I -- Richards, Michael P -- Peristov, Nikolai V -- Lachmann, Michael -- Douka, Katerina -- Higham, Thomas F G -- Slatkin, Montgomery -- Hublin, Jean-Jacques -- Reich, David -- Kelso, Janet -- Viola, T Bence -- Paabo, Svante -- F32 GM115006/GM/NIGMS NIH HHS/ -- GM100233/GM/NIGMS NIH HHS/ -- K99 GM104158/GM/NIGMS NIH HHS/ -- K99-GM104158/GM/NIGMS NIH HHS/ -- R01 GM100233/GM/NIGMS NIH HHS/ -- R01-GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Oct 23;514(7523):445-9. doi: 10.1038/nature13810.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, IVPP, CAS, Beijing 100044, China [2] Department of Evolutionary Genetics, Max Planck Institute for Evolutionary Anthropology, D-04103 Leipzig, Germany. ;

    Description: With the exception of Neanderthals, from which DNA sequences of numerous individuals have now been determined, the number and genetic relationships of other hominin lineages are largely unknown. Here we report a complete mitochondrial (mt) DNA sequence retrieved from a bone excavated in 2008 in Denisova Cave in the Altai Mountains in southern Siberia. It represents a hitherto unknown type of hominin mtDNA that shares a common ancestor with anatomically modern human and Neanderthal mtDNAs about 1.0 million years ago. This indicates that it derives from a hominin migration out of Africa distinct from that of the ancestors of Neanderthals and of modern humans. The stratigraphy of the cave where the bone was found suggests that the Denisova hominin lived close in time and space with Neanderthals as well as with modern humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krause, Johannes -- Fu, Qiaomei -- Good, Jeffrey M -- Viola, Bence -- Shunkov, Michael V -- Derevianko, Anatoli P -- Paabo, Svante -- England -- Nature. 2010 Apr 8;464(7290):894-7. doi: 10.1038/nature08976.

    Description: Excavations of a complex of caves in the Sierra de Atapuerca in northern Spain have unearthed hominin fossils that range in age from the early Pleistocene to the Holocene. One of these sites, the 'Sima de los Huesos' ('pit of bones'), has yielded the world's largest assemblage of Middle Pleistocene hominin fossils, consisting of at least 28 individuals dated to over 300,000 years ago. The skeletal remains share a number of morphological features with fossils classified as Homo heidelbergensis and also display distinct Neanderthal-derived traits. Here we determine an almost complete mitochondrial genome sequence of a hominin from Sima de los Huesos and show that it is closely related to the lineage leading to mitochondrial genomes of Denisovans, an eastern Eurasian sister group to Neanderthals. Our results pave the way for DNA research on hominins from the Middle Pleistocene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Matthias -- Fu, Qiaomei -- Aximu-Petri, Ayinuer -- Glocke, Isabelle -- Nickel, Birgit -- Arsuaga, Juan-Luis -- Martinez, Ignacio -- Gracia, Ana -- de Castro, Jose Maria Bermudez -- Carbonell, Eudald -- Paabo, Svante -- England -- Nature. 2014 Jan 16;505(7483):403-6. doi: 10.1038/nature12788.

    Description: Cytosine residues in mammalian DNA occur in five forms: cytosine (C), 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC). The ten-eleven translocation (Tet) dioxygenases convert 5mC to 5hmC, 5fC and 5caC in three consecutive, Fe(II)- and alpha-ketoglutarate-dependent oxidation reactions. The Tet family of dioxygenases is widely distributed across the tree of life, including in the heterolobosean amoeboflagellate Naegleria gruberi. The genome of Naegleria encodes homologues of mammalian DNA methyltransferase and Tet proteins. Here we study biochemically and structurally one of the Naegleria Tet-like proteins (NgTet1), which shares significant sequence conservation (approximately 14% identity or 39% similarity) with mammalian Tet1. Like mammalian Tet proteins, NgTet1 acts on 5mC and generates 5hmC, 5fC and 5caC. The crystal structure of NgTet1 in complex with DNA containing a 5mCpG site revealed that NgTet1 uses a base-flipping mechanism to access 5mC. The DNA is contacted from the minor groove and bent towards the major groove. The flipped 5mC is positioned in the active-site pocket with planar stacking contacts, Watson-Crick polar hydrogen bonds and van der Waals interactions specific for 5mC. The sequence conservation between NgTet1 and mammalian Tet1, including residues involved in structural integrity and functional significance, suggests structural conservation across phyla.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4364404/" 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/PMC4364404/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hashimoto, Hideharu -- Pais, June E -- Zhang, Xing -- Saleh, Lana -- Fu, Zheng-Qing -- Dai, Nan -- Correa, Ivan R Jr -- Zheng, Yu -- Cheng, Xiaodong -- GM049245/GM/NIGMS NIH HHS/ -- GM095209/GM/NIGMS NIH HHS/ -- GM105132/GM/NIGMS NIH HHS/ -- R01 GM049245/GM/NIGMS NIH HHS/ -- R44 GM105132/GM/NIGMS NIH HHS/ -- England -- Nature. 2014 Feb 20;506(7488):391-5. doi: 10.1038/nature12905.

    Description: Using DNA extracted from a finger bone found in Denisova Cave in southern Siberia, we have sequenced the genome of an archaic hominin to about 1.9-fold coverage. This individual is from a group that shares a common origin with Neanderthals. This population was not involved in the putative gene flow from Neanderthals into Eurasians; however, the data suggest that it contributed 4-6% of its genetic material to the genomes of present-day Melanesians. We designate this hominin population 'Denisovans' and suggest that it may have been widespread in Asia during the Late Pleistocene epoch. A tooth found in Denisova Cave carries a mitochondrial genome highly similar to that of the finger bone. This tooth shares no derived morphological features with Neanderthals or modern humans, further indicating that Denisovans have an evolutionary history distinct from Neanderthals and modern humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4306417/" 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/PMC4306417/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reich, David -- Green, Richard E -- Kircher, Martin -- Krause, Johannes -- Patterson, Nick -- Durand, Eric Y -- Viola, Bence -- Briggs, Adrian W -- Stenzel, Udo -- Johnson, Philip L F -- Maricic, Tomislav -- Good, Jeffrey M -- Marques-Bonet, Tomas -- Alkan, Can -- Fu, Qiaomei -- Mallick, Swapan -- Li, Heng -- Meyer, Matthias -- Eichler, Evan E -- Stoneking, Mark -- Richards, Michael -- Talamo, Sahra -- Shunkov, Michael V -- Derevianko, Anatoli P -- Hublin, Jean-Jacques -- Kelso, Janet -- Slatkin, Montgomery -- Paabo, Svante -- R01 GM040282/GM/NIGMS NIH HHS/ -- R01-GM40282/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Dec 23;468(7327):1053-60. doi: 10.1038/nature09710.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, Massachusetts 02115, USA. reich@genetics.med.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21179161" target="_blank"〉PubMed〈/a〉

    Description: Recent observations show that the rapid fluctuations in radio, hard X-ray, and H-alpha emissions are closely associated with type III and microwave (or decimetric) bursts during the impulsive and/or preimpulsive phases of solar flares. In order to clarify the physical processes of these observed phenomena, this paper proposes a tentative model of two acceleration regions A (source of type III bursts) and B (source of microwave or decimetric bursts) formed in the neutral sheet and at the top of a flaring loop, respectively; and also suggests that the electron beams streaming from region A and/or region B downward to the chromosphere are responsible for the rapid fluctuations in the different emissions mentioned above during the impulsive and/or preimpulsive phases of solar flares.

    Description: VLA observations at 6 and 20 cm wavelengths taken on August 3, 1985 are presented, showing an eruptive filament event in which microwave emission originated in two widely separated regions during the disintegration of the filament. The amount of heat required for the enhancement is estimated. Near-simultaneous changes in intensity and polarization were observed in the western components of the northern and southern regions. It is suggested that large-scale magnetic interconnections permitted the two regions to respond similarly to an external energy or mass source involved in the disruption of the filament.
