ENZYME entry: EC 2.4.1.18

PURL: https://purl.expasy.org/enzyme/EC/2.4.1.18
Accepted Name
1,4-alpha-glucan branching enzyme
Alternative Name(s)
amylo-(1,4->1,6)-transglycosylase
amylo-(1,4 to 1,6)transglucosidase
branching enzyme
glycogen branching enzyme
Reaction catalysed
Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain
Comment(s)
  • Converts amylose into amylopectin.
  • The description (official name) requires a qualification depending on the product, glycogen or amylopectin, e.g. glycogen branching enzyme, amylopectin branching enzyme.
