Web5.2.4.2 Granule bound starch synthases Granule bound starch synthase (GBSS) (EC 2.4.1.242) is a glycosyltransferase, which preferentially transfers a glucosyl residue from ADPG to the non-reducing end of an α-(1,4) linked glucan primer, acting processively, unlike other starch synthases, which act in a distributive manner ( Denyer et al., 1999 ).

Web2.23.6.2 Granule-Bound Starch Synthase. GBSS is responsible for amylose biosynthesis. This group of enzymes was described by Leloir and his colleagues 42–44 and other researchers. 45,46 Waxy mutants of maize defective for GBSS contain wild-type amounts of starch with no amylose. 45 Similar waxy mutants have been obtained in other species ... WebUnlike EC 2.4.1.11 and EC 2.4.1.21 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 …
