A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC

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
  • 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).
