    Crystal structure of the ATP-gated P2X(4) ion channel in the closed state (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-31
    Description: P2X receptors are cation-selective ion channels gated by extracellular ATP, and are implicated in diverse physiological processes, from synaptic transmission to inflammation to the sensing of taste and pain. Because P2X receptors are not related to other ion channel proteins of known structure, there is at present no molecular foundation for mechanisms of ligand-gating, allosteric modulation and ion permeation. Here we present crystal structures of the zebrafish P2X(4) receptor in its closed, resting state. The chalice-shaped, trimeric receptor is knit together by subunit-subunit contacts implicated in ion channel gating and receptor assembly. Extracellular domains, rich in beta-strands, have large acidic patches that may attract cations, through fenestrations, to vestibules near the ion channel. In the transmembrane pore, the 'gate' is defined by an approximately 8 A slab of protein. We define the location of three non-canonical, intersubunit ATP-binding sites, and suggest that ATP binding promotes subunit rearrangement and ion channel opening.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2720809/" 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/PMC2720809/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kawate, Toshimitsu -- Michel, Jennifer Carlisle -- Birdsong, William T -- Gouaux, Eric -- U54 GM075026/GM/NIGMS NIH HHS/ -- U54 GM075026-04/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Jul 30;460(7255):592-8. doi: 10.1038/nature08198.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vollum Institute, Oregon Health and Science University, 3181 Southwest Sam Jackson Park Road, Oregon 97239, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19641588" target="_blank"〉PubMed〈/a〉

    Predicting new molecular targets for known drugs (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-03
    Description: Although drugs are intended to be selective, at least some bind to several physiological targets, explaining side effects and efficacy. Because many drug-target combinations exist, it would be useful to explore possible interactions computationally. Here we compared 3,665 US Food and Drug Administration (FDA)-approved and investigational drugs against hundreds of targets, defining each target by its ligands. Chemical similarities between drugs and ligand sets predicted thousands of unanticipated associations. Thirty were tested experimentally, including the antagonism of the beta(1) receptor by the transporter inhibitor Prozac, the inhibition of the 5-hydroxytryptamine (5-HT) transporter by the ion channel drug Vadilex, and antagonism of the histamine H(4) receptor by the enzyme inhibitor Rescriptor. Overall, 23 new drug-target associations were confirmed, five of which were potent (〈100 nM). The physiological relevance of one, the drug N,N-dimethyltryptamine (DMT) on serotonergic receptors, was confirmed in a knockout mouse. The chemical similarity approach is systematic and comprehensive, and may suggest side-effects and new indications for many drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2784146/" 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/PMC2784146/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keiser, Michael J -- Setola, Vincent -- Irwin, John J -- Laggner, Christian -- Abbas, Atheir I -- Hufeisen, Sandra J -- Jensen, Niels H -- Kuijer, Michael B -- Matos, Roberto C -- Tran, Thuy B -- Whaley, Ryan -- Glennon, Richard A -- Hert, Jerome -- Thomas, Kelan L H -- Edwards, Douglas D -- Shoichet, Brian K -- Roth, Bryan L -- R01 DA017204/DA/NIDA NIH HHS/ -- R01 DA017204-04/DA/NIDA NIH HHS/ -- R01 DA017204-05/DA/NIDA NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH061887-09/MH/NIMH NIH HHS/ -- R01 MH061887-10/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH082441-01/MH/NIMH NIH HHS/ -- U19 MH082441-010001/MH/NIMH NIH HHS/ -- U19 MH082441-019002/MH/NIMH NIH HHS/ -- U19 MH082441-019003/MH/NIMH NIH HHS/ -- U19 MH082441-02/MH/NIMH NIH HHS/ -- U19 MH082441-020001/MH/NIMH NIH HHS/ -- U19 MH082441-029002/MH/NIMH NIH HHS/ -- U19 MH082441-03/MH/NIMH NIH HHS/ -- U19 MH082441-030001/MH/NIMH NIH HHS/ -- U19 MH082441-039002/MH/NIMH NIH HHS/ -- England -- Nature. 2009 Nov 12;462(7270):175-81. doi: 10.1038/nature08506.

    Molecular basis of transport and regulation in the Na(+)/betaine symporter BetP (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-03-06
    Description: Osmoregulated transporters sense intracellular osmotic pressure and respond to hyperosmotic stress by accumulation of osmolytes to restore normal hydration levels. Here we report the determination of the X-ray structure of a member of the family of betaine/choline/carnitine transporters, the Na(+)-coupled symporter BetP from Corynebacterium glutamicum, which is a highly effective osmoregulated uptake system for glycine betaine. Glycine betaine is bound in a tryptophan box occluded from both sides of the membrane with aromatic side chains lining the transport pathway. BetP has the same overall fold as three unrelated Na(+)-coupled symporters. Whereas these are crystallized in either the outward-facing or the inward-facing conformation, the BetP structure reveals a unique intermediate conformation in the Na(+)-coupled transport cycle. The trimeric architecture of BetP and the break in three-fold symmetry by the osmosensing C-terminal helices suggest a regulatory mechanism of Na(+)-coupled osmolyte transport to counteract osmotic stress.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ressl, Susanne -- Terwisscha van Scheltinga, Anke C -- Vonrhein, Clemens -- Ott, Vera -- Ziegler, Christine -- England -- Nature. 2009 Mar 5;458(7234):47-52. doi: 10.1038/nature07819.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute of Biophysics, Department of Structural Biology, 60438 Frankfurt am Main, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19262666" target="_blank"〉PubMed〈/a〉

    Rational design of a structural and functional nitric oxide reductase (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-27
    Description: Protein design provides a rigorous test of our knowledge about proteins and allows the creation of novel enzymes for biotechnological applications. Whereas progress has been made in designing proteins that mimic native proteins structurally, it is more difficult to design functional proteins. In comparison to recent successes in designing non-metalloproteins, it is even more challenging to rationally design metalloproteins that reproduce both the structure and function of native metalloenzymes. This is because protein metal-binding sites are much more varied than non-metal-containing sites, in terms of different metal ion oxidation states, preferred geometry and metal ion ligand donor sets. Because of their variability, it has been difficult to predict metal-binding site properties in silico, as many of the parameters, such as force fields, are ill-defined. Therefore, the successful design of a structural and functional metalloprotein would greatly advance the field of protein design and our understanding of enzymes. Here we report a successful, rational design of a structural and functional model of a metalloprotein, nitric oxide reductase (NOR), by introducing three histidines and one glutamate, predicted as ligands in the active site of NOR, into the distal pocket of myoglobin. A crystal structure of the designed protein confirms that the minimized computer model contains a haem/non-haem Fe(B) centre that is remarkably similar to that in the crystal structure. This designed protein also exhibits NO reduction activity, and so models both the structure and function of NOR, offering insight that the active site glutamate is required for both iron binding and activity. These results show that structural and functional metalloproteins can be rationally designed in silico.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4297211/" 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/PMC4297211/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yeung, Natasha -- Lin, Ying-Wu -- Gao, Yi-Gui -- Zhao, Xuan -- Russell, Brandy S -- Lei, Lanyu -- Miner, Kyle D -- Robinson, Howard -- Lu, Yi -- GM062211/GM/NIGMS NIH HHS/ -- R01 GM062211/GM/NIGMS NIH HHS/ -- England -- Nature. 2009 Dec 24;462(7276):1079-82. doi: 10.1038/nature08620.

    Transport mechanism of a bacterial homologue of glutamate transporters (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-20
    Description: Glutamate transporters are integral membrane proteins that catalyse a thermodynamically uphill uptake of the neurotransmitter glutamate from the synaptic cleft into the cytoplasm of glia and neuronal cells by harnessing the energy of pre-existing electrochemical gradients of ions. Crucial to the reaction is the conformational transition of the transporters between outward and inward facing states, in which the substrate binding sites are accessible from the extracellular space and the cytoplasm, respectively. Here we describe the crystal structure of a double cysteine mutant of a glutamate transporter homologue from Pyrococcus horikoshii, Glt(Ph), which is trapped in the inward facing state by cysteine crosslinking. Together with the previously determined crystal structures of Glt(Ph) in the outward facing state, the structure of the crosslinked mutant allows us to propose a molecular mechanism by which Glt(Ph) and, by analogy, mammalian glutamate transporters mediate sodium-coupled substrate uptake.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2934767/" 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/PMC2934767/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reyes, Nicolas -- Ginter, Christopher -- Boudker, Olga -- R01 NS064357/NS/NINDS NIH HHS/ -- R01 NS064357-01A1/NS/NINDS NIH HHS/ -- England -- Nature. 2009 Dec 17;462(7275):880-5. doi: 10.1038/nature08616.
