IntEnz Enzyme Nomenclature


Accepted name:
α-1,4-glucan-protein synthase (ADP-forming)
Other names:
ADPglucose:protein 4-α-D-glucosyltransferase
ADPglucose:protein glucosyltransferase
adenosine diphosphoglucose-protein glucosyltransferase
Systematic name:
ADP-glucose:protein 4-α-D-glucosyltransferase



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