Term Name:	alpha-1,4-glucan glucosyltransferase (NDP-glucose donor) activity
Synonyms:	GBSS, GBSSI, GBSSII, granule-bound starch synthase activity, granule-bound starch synthase I activity, granule-bound starch synthase II activity, NDP-glucose:1,4-alpha-D-glucan 4-alpha-D-glucosyltransferase activity, NDPglucose-starch glucosyltransferase activity, starch granule-bound nucleoside diphosphate glucose-starch glucosyltransferase activity, starch synthase II activity, waxy protein
Definition:	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.
