SYSTEMATIC NAME
IUBMB Comments
NDP-glucose:(1->4)-alpha-D-glucan 4-alpha-D-glucosyltransferase
Unlike EC 2.4.1.11, glycogen(starch) synthase and EC 2.4.1.21, starch synthase, which use UDP-glucose and ADP-glucose, respectively, this enzyme can use either UDP- or ADP-glucose. Mutants that lack the Wx (waxy) allele cannot produce this enzyme, which plays an important role in the normal synthesis of amylose. In such mutants, only amylopectin is produced in the endosperm [3] or pollen [5].
