    Modest stabilization by most hydrogen-bonded side-chain interactions in membrane proteins (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-05-27
    Beschreibung: Understanding the energetics of molecular interactions is fundamental to all of the central quests of structural biology including structure prediction and design, mapping evolutionary pathways, learning how mutations cause disease, drug design, and relating structure to function. Hydrogen-bonding is widely regarded as an important force in a membrane environment because of the low dielectric constant of membranes and a lack of competition from water. Indeed, polar residue substitutions are the most common disease-causing mutations in membrane proteins. Because of limited structural information and technical challenges, however, there have been few quantitative tests of hydrogen-bond strength in the context of large membrane proteins. Here we show, by using a double-mutant cycle analysis, that the average contribution of eight interhelical side-chain hydrogen-bonding interactions throughout bacteriorhodopsin is only 0.6 kcal mol(-1). In agreement with these experiments, we find that 4% of polar atoms in the non-polar core regions of membrane proteins have no hydrogen-bond partner and the lengths of buried hydrogen bonds in soluble proteins and membrane protein transmembrane regions are statistically identical. Our results indicate that most hydrogen-bond interactions in membrane proteins are only modestly stabilizing. Weak hydrogen-bonding should be reflected in considerations of membrane protein folding, dynamics, design, evolution and function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2734483/" 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/PMC2734483/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joh, Nathan Hyunjoong -- Min, Andrew -- Faham, Salem -- Whitelegge, Julian P -- Yang, Duan -- Woods, Virgil L -- Bowie, James U -- R01 CA081000/CA/NCI NIH HHS/ -- R01 CA081000-07/CA/NCI NIH HHS/ -- R01 CA081000-08/CA/NCI NIH HHS/ -- R01 CA081000-09/CA/NCI NIH HHS/ -- R01 GM063919/GM/NIGMS NIH HHS/ -- R01 GM063919-06/GM/NIGMS NIH HHS/ -- R01 GM063919-07/GM/NIGMS NIH HHS/ -- R01 GM063919-08/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Jun 26;453(7199):1266-70. doi: 10.1038/nature06977.

    An architectural framework that may lie at the core of the postsynaptic density (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2006-01-28
    Beschreibung: The postsynaptic density (PSD) is a complex assembly of proteins associated with the postsynaptic membrane that organizes neurotransmitter receptors, signaling pathways, and regulatory elements within a cytoskeletal matrix. Here we show that the sterile alpha motif domain of rat Shank3/ProSAP2, a master scaffolding protein located deep within the PSD, can form large sheets composed of helical fibers stacked side by side. Zn2+, which is found in high concentrations in the PSD, binds tightly to Shank3 and may regulate assembly. Sheets of the Shank protein could form a platform for the construction of the PSD complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baron, Marisa K -- Boeckers, Tobias M -- Vaida, Bianca -- Faham, Salem -- Gingery, Mari -- Sawaya, Michael R -- Salyer, Danielle -- Gundelfinger, Eckart D -- Bowie, James U -- R01 CA081000/CA/NCI NIH HHS/ -- R01 GM063919/GM/NIGMS NIH HHS/ -- R01 GM063919-07/GM/NIGMS NIH HHS/ -- R01 GM063919-08/GM/NIGMS NIH HHS/ -- R01 GM075922/GM/NIGMS NIH HHS/ -- R01 GM075922-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Jan 27;311(5760):531-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biochemistry, Molecular Biology Institute, University of California, Los Angeles, 611 Charles E.
