IUBMB Enzyme Nomenclature


Accepted name: α-1,4-glucan-protein synthase (ADP-forming)

Reaction: ADP-glucose + protein = ADP + α-D-glucosyl-protein

Other name(s): ADP-glucose:protein glucosyltransferase; adenosine diphosphoglucose-protein glucosyltransferase

Systematic name: ADP-glucose:protein 4-α-D-glucosyltransferase

Comments: The enzyme builds up α-1,4-glucan chains covalently bound to protein, thus acting as an initiator of glycogen synthesis.
