Superfamily	Glycogen Phosphorylase B;
Functional Family	Starch synthase, chloroplastic/amyloplastic

Enzyme Information

2.4.1.242

NDP-glucose--starch glucosyltransferase.

based on mapping to UniProt Q0DEV5

NDP-alpha-D-glucose + ((1->4)-alpha-D-glucosyl)(n) = NDP + ((1->4)-alpha- D-glucosyl)(n+1).

-!- Unlike 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 or pollen.
