Functional characterization of alpha-glucan,water dikinase, the starch phosphorylating enzyme.

The Biochemical journal - 15 Jan 2004

Mikkelsen René, Baunsgaard Lone, Blennow Andreas

Abstract excerpt

GWD (alpha-glucan,water dikinase) is the enzyme that catalyses the phosphorylation of starch by a dikinase-type reaction in which the beta-phosphate of ATP is transferred to either the C-6 or the C-3 position of the glycosyl residue of amylopectin. GWD shows similarity in both sequence and reaction mechanism to bacterial PPS (pyruvate,water dikinase) and PPDK (pyruvate,phosphate dikinase). Amino acid sequence...
