ENZYME entry: EC 2.4.1.21

PURL: https://purl.expasy.org/enzyme/EC/2.4.1.21
Accepted Name
starch synthase
Alternative Name(s)
ADP-glucose--starch glucosyltransferase
glycogen synthase
starch (bacterial glycogen) synthase
Reaction catalysed
[(1->4)-alpha-D-glucosyl](n) + ADP-alpha-D-glucose = [(1->4)-alpha-D-glucosyl](n+1) + ADP + H(+)
Comment(s)
  • The description (accepted name) varies according to the source of the enzyme and the nature of its synthetic product, e.g. starch synthase, bacterial glycogen synthase.
  • A similar enzyme utilizes UDP-alpha-D-glucose (cf. EC 2.4.1.11).
