ENZYME entry: EC 2.4.1.13

Accepted Name
Sucrose synthase.
Alternative Name(s)
Sucrose synthetase.
Sucrose-UDP glucosyltransferase.
Sucrose-uridine diphosphate glucosyltransferase.
UDP-glucose-fructose glucosyltransferase.
Uridine diphosphoglucose-fructose glucosyltransferase.
Reaction catalysed
NDP-glucose + D-fructose <=> NDP + sucrose
Comment(s)
  • 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).
