Mechanistic implications for Escherichia coli cofactor-dependent phosphoglycerate mutase based on the high-resolution crystal structure of a vanadate complex.

Abstract excerpt

The structure of Escherichia coli cofactor-dependent phosphoglycerate mutase (dPGM), complexed with the potent inhibitor vanadate, has been determined to a resolution of 1.30 A (R-factor 0.159; R-free 0.213). The inhibitor is present in the active site, principally as divanadate, but with evidence of additional vanadate moieties at either end, and representing a different binding mode to that observed in the...
