PHOSPHATE-BINDING PROTEIN MUTANT WITH ASP 56 REPLACED BY ASN COMPLEX WITH MONOBASIC PHOSPHATE ION

Overview

A 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.
