Enzyme Information

2.4.1.13

Sucrose synthase.

based on mapping to UniProt Q820M5

NDP-glucose + D-fructose = NDP + sucrose.

-!- Although UDP is generally considered to be the preferred nucleoside diphosphate for sucrose synthase, numerous studies have shown that ADP serves as an effective acceptor molecule to produce ADP-glucose. -!- Sucrose synthase has a dual role in producing both UDP-glucose (necessary for cell wall and glycoprotein biosynthesis) and ADP- glucose (necessary for starch biosynthesis).
