label: alpha-1,4-glucan glucosyltransferase (NDP-glucose donor) activity
label_lc: alpha-1,4-glucan glucosyltransferase (ndp-glucose donor) activity
description: "Catalysis of the reaction: [(1->4)-alpha-D-glucosyl](n) + an NDP-alpha-D-glucose = [(1->4)-alpha-D-glucosyl](n+1) + a ribonucleoside 5'-diphosphate + H+, where NDP is ADP or UDP."
