Mechanisms of Activation of Phosphoenolpyruvate Carboxykinase from Escherichia coli by Ca(2+) and of Desensitization by Trypsin
The 1.8-Å resolution structure of the ATP-Mg(2+)-Ca(2+)-pyruvate quinary complex of Escherichia coli phosphoenolpyruvate carboxykinase (PCK) is isomorphous to the published complex ATP-Mg(2+)-Mn(2+)-pyruvate-PCK, except for the Ca(2+) and Mn(2+) binding sites. Ca(2+) was formerly implicated as a pos...
