    Description: Voltage-gated sodium (Nav) channels propagate action potentials in excitable cells. Accordingly, Nav channels are therapeutic targets for many cardiovascular and neurological disorders. Selective inhibitors have been challenging to design because the nine mammalian Nav channel isoforms share high sequence identity and remain recalcitrant to high-resolution structural studies. Targeting the human Nav1.7 channel involved in pain perception, we present a protein-engineering strategy that has allowed us to determine crystal structures of a novel receptor site in complex with isoform-selective antagonists. GX-936 and related inhibitors bind to the activated state of voltage-sensor domain IV (VSD4), where their anionic aryl sulfonamide warhead engages the fourth arginine gating charge on the S4 helix. By opposing VSD4 deactivation, these compounds inhibit Nav1.7 through a voltage-sensor trapping mechanism, likely by stabilizing inactivated states of the channel. Residues from the S2 and S3 helices are key determinants of isoform selectivity, and bound phospholipids implicate the membrane as a modulator of channel function and pharmacology. Our results help to elucidate the molecular basis of voltage sensing and establish structural blueprints to design selective Nav channel antagonists.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahuja, Shivani -- Mukund, Susmith -- Deng, Lunbin -- Khakh, Kuldip -- Chang, Elaine -- Ho, Hoangdung -- Shriver, Stephanie -- Young, Clint -- Lin, Sophia -- Johnson, J P Jr -- Wu, Ping -- Li, Jun -- Coons, Mary -- Tam, Christine -- Brillantes, Bobby -- Sampang, Honorio -- Mortara, Kyle -- Bowman, Krista K -- Clark, Kevin R -- Estevez, Alberto -- Xie, Zhiwei -- Verschoof, Henry -- Grimwood, Michael -- Dehnhardt, Christoph -- Andrez, Jean-Christophe -- Focken, Thilo -- Sutherlin, Daniel P -- Safina, Brian S -- Starovasnik, Melissa A -- Ortwine, Daniel F -- Franke, Yvonne -- Cohen, Charles J -- Hackos, David H -- Koth, Christopher M -- Payandeh, Jian -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):aac5464. doi: 10.1126/science.aac5464.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Neuroscience, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Biology, Xenon Pharmaceuticals Inc., Burnaby, British Columbia, V5G 4W8, Canada. ; Department of Discovery Chemistry, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Biochemical and Cellular Pharmacology, Genentech Inc., South San Francisco, CA 94080, USA. ; Department of Chemistry, Xenon Pharmaceuticals Inc., Burnaby, British Columbia, V5G 4W8, Canada. ; Department of Neuroscience, Genentech Inc., South San Francisco, CA 94080, USA. hackos.david@gene.com koth.christopher@gene.com payandeh.jian@gene.com. ; Department of Structural Biology, Genentech Inc., South San Francisco, CA 94080, USA. hackos.david@gene.com koth.christopher@gene.com payandeh.jian@gene.com.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26680203" target="_blank"〉PubMed〈/a〉

    Description: Telomerase helps maintain telomeres by processive synthesis of telomere repeat DNA at their 3'-ends, using an integral telomerase RNA (TER) and telomerase reverse transcriptase (TERT). We report the cryo-electron microscopy structure of Tetrahymena telomerase at ~9 angstrom resolution. In addition to seven known holoenzyme proteins, we identify two additional proteins that form a complex (TEB) with single-stranded telomere DNA-binding protein Teb1, paralogous to heterotrimeric replication protein A (RPA). The p75-p45-p19 subcomplex is identified as another RPA-related complex, CST (CTC1-STN1-TEN1). This study reveals the paths of TER in the TERT-TER-p65 catalytic core and single-stranded DNA exit; extensive subunit interactions of the TERT essential N-terminal domain, p50, and TEB; and other subunit identities and structures, including p19 and p45C crystal structures. Our findings provide structural and mechanistic insights into telomerase holoenzyme function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4687456/" 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/PMC4687456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Jiansen -- Chan, Henry -- Cash, Darian D -- Miracco, Edward J -- Ogorzalek Loo, Rachel R -- Upton, Heather E -- Cascio, Duilio -- O'Brien Johnson, Reid -- Collins, Kathleen -- Loo, Joseph A -- Zhou, Z Hong -- Feigon, Juli -- GM007185/GM/NIGMS NIH HHS/ -- GM048123/GM/NIGMS NIH HHS/ -- GM071940/GM/NIGMS NIH HHS/ -- GM101874/GM/NIGMS NIH HHS/ -- GM103479/GM/NIGMS NIH HHS/ -- P41 GM103403/GM/NIGMS NIH HHS/ -- P41 RR015301/RR/NCRR NIH HHS/ -- R01 GM048123/GM/NIGMS NIH HHS/ -- R01 GM054198/GM/NIGMS NIH HHS/ -- R01 GM071940/GM/NIGMS NIH HHS/ -- R01 GM103479/GM/NIGMS NIH HHS/ -- R01GM054198/GM/NIGMS NIH HHS/ -- S10OD018111/OD/NIH HHS/ -- S10RR23057/RR/NCRR NIH HHS/ -- UL1TR000124/TR/NCATS NIH HHS/ -- New York, N.Y. -- Science. 2015 Oct 30;350(6260):aab4070. doi: 10.1126/science.aab4070.

    Description: Microbial sulfate reduction has governed Earth's biogeochemical sulfur cycle for at least 2.5 billion years. However, the enzymatic mechanisms behind this pathway are incompletely understood, particularly for the reduction of sulfite-a key intermediate in the pathway. This critical reaction is performed by DsrAB, a widespread enzyme also involved in other dissimilatory sulfur metabolisms. Using in vitro assays with an archaeal DsrAB, supported with genetic experiments in a bacterial system, we show that the product of sulfite reduction by DsrAB is a protein-based trisulfide, in which a sulfite-derived sulfur is bridging two conserved cysteines of DsrC. Physiological studies also reveal that sulfate reduction rates are determined by cellular levels of DsrC. Dissimilatory sulfate reduction couples the four-electron reduction of the DsrC trisulfide to energy conservation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Santos, Andre A -- Venceslau, Sofia S -- Grein, Fabian -- Leavitt, William D -- Dahl, Christiane -- Johnston, David T -- Pereira, Ines A C -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):1541-5. doi: 10.1126/science.aad3558.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Instituto de Tecnologia Quimica e Biologica Antonio Xavier, Universidade Nova de Lisboa, Oeiras, Portugal. ; Department of Earth and Planetary Science, Harvard University, Cambridge, MA, USA. ; Institut fur Mikrobiologie & Biotechnologie, Rheinische Friedrich-Wilhelms-Universitat Bonn, Germany. ; Instituto de Tecnologia Quimica e Biologica Antonio Xavier, Universidade Nova de Lisboa, Oeiras, Portugal. ipereira@itqb.unl.pt.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26680199" target="_blank"〉PubMed〈/a〉

    Description: The fleeting lifetimes of the transition states (TSs) of chemical reactions make determination of their three-dimensional structures by diffraction methods a challenge. Here, we used packing interactions within the core of a protein to stabilize the planar TS conformation for rotation around the central carbon-carbon bond of biphenyl so that it could be directly observed by x-ray crystallography. The computational protein design software Rosetta was used to design a pocket within threonyl-transfer RNA synthetase from the thermophile Pyrococcus abyssi that forms complementary van der Waals interactions with a planar biphenyl. This latter moiety was introduced biosynthetically as the side chain of the noncanonical amino acid p-biphenylalanine. Through iterative rounds of computational design and structural analysis, we identified a protein in which the side chain of p-biphenylalanine is trapped in the energetically disfavored, coplanar conformation of the TS of the bond rotation reaction.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4581533/" 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/PMC4581533/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearson, Aaron D -- Mills, Jeremy H -- Song, Yifan -- Nasertorabi, Fariborz -- Han, Gye Won -- Baker, David -- Stevens, Raymond C -- Schultz, Peter G -- 2 R01 GM097206-05/GM/NIGMS NIH HHS/ -- F32 GM099210/GM/NIGMS NIH HHS/ -- F32GM099210/GM/NIGMS NIH HHS/ -- R01 GM097206/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):863-7. doi: 10.1126/science.aaa2424.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Skaggs Institute for Chemical Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. ; Department of Biochemistry, University of Washington, Seattle, WA 98195, USA. ; Department of Biological Sciences, Bridge Institute, University of Southern California, Los Angeles, CA 90089, USA. ; Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.

    Description: Nucleotide analog inhibitors have shown clinical success in the treatment of hepatitis C virus (HCV) infection, despite an incomplete mechanistic understanding of NS5B, the viral RNA-dependent RNA polymerase. Here we study the details of HCV RNA replication by determining crystal structures of stalled polymerase ternary complexes with enzymes, RNA templates, RNA primers, incoming nucleotides, and catalytic metal ions during both primed initiation and elongation of RNA synthesis. Our analysis revealed that highly conserved active-site residues in NS5B position the primer for in-line attack on the incoming nucleotide. A beta loop and a C-terminal membrane-anchoring linker occlude the active-site cavity in the apo state, retract in the primed initiation assembly to enforce replication of the HCV genome from the 3' terminus, and vacate the active-site cavity during elongation. We investigated the incorporation of nucleotide analog inhibitors, including the clinically active metabolite formed by sofosbuvir, to elucidate key molecular interactions in the active site.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Appleby, Todd C -- Perry, Jason K -- Murakami, Eisuke -- Barauskas, Ona -- Feng, Joy -- Cho, Aesop -- Fox, David 3rd -- Wetmore, Diana R -- McGrath, Mary E -- Ray, Adrian S -- Sofia, Michael J -- Swaminathan, S -- Edwards, Thomas E -- New York, N.Y. -- Science. 2015 Feb 13;347(6223):771-5. doi: 10.1126/science.1259210.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gilead Sciences, 333 Lakeside Drive, Foster City, CA 94404, USA. todd.appleby@gilead.com tedwards@be4.com. ; Gilead Sciences, 333 Lakeside Drive, Foster City, CA 94404, USA. ; Beryllium, 7869 NE Day Road West, Bainbridge Island, WA 98110, USA. ; Beryllium, 7869 NE Day Road West, Bainbridge Island, WA 98110, USA. todd.appleby@gilead.com tedwards@be4.com.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25678663" target="_blank"〉PubMed〈/a〉

    Description: Anion exchanger 1 (AE1), also known as band 3 or SLC4A1, plays a key role in the removal of carbon dioxide from tissues by facilitating the exchange of chloride and bicarbonate across the plasma membrane of erythrocytes. An isoform of AE1 is also present in the kidney. Specific mutations in human AE1 cause several types of hereditary hemolytic anemias and/or distal renal tubular acidosis. Here we report the crystal structure of the band 3 anion exchanger domain (AE1(CTD)) at 3.5 angstroms. The structure is locked in an outward-facing open conformation by an inhibitor. Comparing this structure with a substrate-bound structure of the uracil transporter UraA in an inward-facing conformation allowed us to identify the anion-binding position in the AE1(CTD), and to propose a possible transport mechanism that could explain why selected mutations lead to disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arakawa, Takatoshi -- Kobayashi-Yurugi, Takami -- Alguel, Yilmaz -- Iwanari, Hiroko -- Hatae, Hinako -- Iwata, Momi -- Abe, Yoshito -- Hino, Tomoya -- Ikeda-Suno, Chiyo -- Kuma, Hiroyuki -- Kang, Dongchon -- Murata, Takeshi -- Hamakubo, Takao -- Cameron, Alexander D -- Kobayashi, Takuya -- Hamasaki, Naotaka -- Iwata, So -- BB/D019516/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G023425/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- WT089809/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2015 Nov 6;350(6261):680-4. doi: 10.1126/science.aaa4335.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Japan Science and Technology Agency (JST), Exploratory Research for Advanced Technology (ERATO) Human Receptor Crystallography Project, Konoe-cho, Yoshida, Sakyo-ku, Kyoto 606-8501, Japan.

    Description: The discovery of Streptomyces-produced streptomycin founded the age of tuberculosis therapy. Despite the subsequent development of a curative regimen for this disease, tuberculosis remains a worldwide problem, and the emergence of multidrug-resistant Mycobacterium tuberculosis has prioritized the need for new drugs. Here we show that new optimized derivatives from Streptomyces-derived griselimycin are highly active against M. tuberculosis, both in vitro and in vivo, by inhibiting the DNA polymerase sliding clamp DnaN. We discovered that resistance to griselimycins, occurring at very low frequency, is associated with amplification of a chromosomal segment containing dnaN, as well as the ori site. Our results demonstrate that griselimycins have high translational potential for tuberculosis treatment, validate DnaN as an antimicrobial target, and capture the process of antibiotic pressure-induced gene amplification.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kling, Angela -- Lukat, Peer -- Almeida, Deepak V -- Bauer, Armin -- Fontaine, Evelyne -- Sordello, Sylvie -- Zaburannyi, Nestor -- Herrmann, Jennifer -- Wenzel, Silke C -- Konig, Claudia -- Ammerman, Nicole C -- Barrio, Maria Belen -- Borchers, Kai -- Bordon-Pallier, Florence -- Bronstrup, Mark -- Courtemanche, Gilles -- Gerlitz, Martin -- Geslin, Michel -- Hammann, Peter -- Heinz, Dirk W -- Hoffmann, Holger -- Klieber, Sylvie -- Kohlmann, Markus -- Kurz, Michael -- Lair, Christine -- Matter, Hans -- Nuermberger, Eric -- Tyagi, Sandeep -- Fraisse, Laurent -- Grosset, Jacques H -- Lagrange, Sophie -- Muller, Rolf -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jun 5;348(6239):1106-12. doi: 10.1126/science.aaa4690.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbial Natural Products, Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), Helmholtz Centre for Infection Research and Pharmaceutical Biotechnology, Saarland University, 66123 Saarbrucken, Germany.

    Description: Chemokines are small proteins that function as immune modulators through activation of chemokine G protein-coupled receptors (GPCRs). Several viruses also encode chemokines and chemokine receptors to subvert the host immune response. How protein ligands activate GPCRs remains unknown. We report the crystal structure at 2.9 angstrom resolution of the human cytomegalovirus GPCR US28 in complex with the chemokine domain of human CX3CL1 (fractalkine). The globular body of CX3CL1 is perched on top of the US28 extracellular vestibule, whereas its amino terminus projects into the central core of US28. The transmembrane helices of US28 adopt an active-state-like conformation. Atomic-level simulations suggest that the agonist-independent activity of US28 may be due to an amino acid network evolved in the viral GPCR to destabilize the receptor's inactive state.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4445376/" 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/PMC4445376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burg, John S -- Ingram, Jessica R -- Venkatakrishnan, A J -- Jude, Kevin M -- Dukkipati, Abhiram -- Feinberg, Evan N -- Angelini, Alessandro -- Waghray, Deepa -- Dror, Ron O -- Ploegh, Hidde L -- Garcia, K Christopher -- DP1 GM106409/GM/NIGMS NIH HHS/ -- R01 GM097015/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Mar 6;347(6226):1113-7. doi: 10.1126/science.aaa5026.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Stanford University School of Medicine, Stanford, CA 94305, USA.

    Description: NADPH/NADP(+) (the reduced form of NADP(+)/nicotinamide adenine dinucleotide phosphate) homeostasis is critical for countering oxidative stress in cells. Nicotinamide nucleotide transhydrogenase (TH), a membrane enzyme present in both bacteria and mitochondria, couples the proton motive force to the generation of NADPH. We present the 2.8 A crystal structure of the transmembrane proton channel domain of TH from Thermus thermophilus and the 6.9 A crystal structure of the entire enzyme (holo-TH). The membrane domain crystallized as a symmetric dimer, with each protomer containing a putative proton channel. The holo-TH is a highly asymmetric dimer with the NADP(H)-binding domain (dIII) in two different orientations. This unusual arrangement suggests a catalytic mechanism in which the two copies of dIII alternatively function in proton translocation and hydride transfer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4479213/" 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/PMC4479213/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leung, Josephine H -- Schurig-Briccio, Lici A -- Yamaguchi, Mutsuo -- Moeller, Arne -- Speir, Jeffrey A -- Gennis, Robert B -- Stout, Charles D -- 1R01GM103838-01A1/GM/NIGMS NIH HHS/ -- 5R01GM061545/GM/NIGMS NIH HHS/ -- GM073197/GM/NIGMS NIH HHS/ -- GM095600/GM/NIGMS NIH HHS/ -- P41 GM103310/GM/NIGMS NIH HHS/ -- P41GM103310/GM/NIGMS NIH HHS/ -- R01 GM061545/GM/NIGMS NIH HHS/ -- R01 GM095600/GM/NIGMS NIH HHS/ -- R01 GM103838/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Jan 9;347(6218):178-81. doi: 10.1126/science.1260451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Structural and Computational Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. ; Department of Biochemistry, University of Illinois, Urbana, IL 61801, USA. ; National Resource for Automated Molecular Microscopy, The Scripps Research Institute, La Jolla, CA 92037, USA. ; Department of Integrative Structural and Computational Biology, The Scripps Research Institute, La Jolla, CA 92037, USA. dave@scripps.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25574024" target="_blank"〉PubMed〈/a〉

    Description: Pigment-protein and pigment-pigment interactions are of fundamental importance to the light-harvesting and photoprotective functions essential to oxygenic photosynthesis. The orange carotenoid protein (OCP) functions as both a sensor of light and effector of photoprotective energy dissipation in cyanobacteria. We report the atomic-resolution structure of an active form of the OCP consisting of the N-terminal domain and a single noncovalently bound carotenoid pigment. The crystal structure, combined with additional solution-state structural data, reveals that OCP photoactivation is accompanied by a 12 angstrom translocation of the pigment within the protein and a reconfiguration of carotenoid-protein interactions. Our results identify the origin of the photochromic changes in the OCP triggered by light and reveal the structural determinants required for interaction with the light-harvesting antenna during photoprotection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leverenz, Ryan L -- Sutter, Markus -- Wilson, Adjele -- Gupta, Sayan -- Thurotte, Adrien -- Bourcier de Carbon, Celine -- Petzold, Christopher J -- Ralston, Corie -- Perreau, Francois -- Kirilovsky, Diana -- Kerfeld, Cheryl A -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Jun 26;348(6242):1463-6. doi: 10.1126/science.aaa7234.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MSU-DOE Plant Research Laboratory, Michigan State University, East Lansing, MI 48824, USA. ; MSU-DOE Plant Research Laboratory, Michigan State University, East Lansing, MI 48824, USA.
