FunctionPSTS_ECOLI Part of the ABC transporter complex PstSACB involved in phosphate import. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedA very short hydrogen bond between an Asp and a phosphate is established in two high resolution structures (0.98 and 1.05 A). A mutant complex that changes the Asp to an Asn, which forms a normal hydrogen bond, has a similar free energy of binding to the wild type complex, suggesting that the contribution of the short hydrogen bond is not extraordinarily strong. A low energy short hydrogen bond in very high resolution structures of protein receptor--phosphate complexes.,Wang Z, Luecke H, Yao N, Quiocho FA Nat Struct Biol. 1997 Jul;4(7):519-22.
