ENZYME entry: EC 2.4.1.125

PURL: https://purl.expasy.org/enzyme/EC/2.4.1.125
Accepted Name
sucrose--1,6-alpha-glucan 3(6)-alpha-glucosyltransferase
Alternative Name(s)
water-soluble-glucan synthase
Reaction catalysed
  • [(1->6)-alpha-D-glucosyl](n) + sucrose = [(1->6)-alpha-D-glucosyl](n+1) + D-fructose
  • [(1->6)-alpha-D-glucosyl](n) + sucrose = (1->3)-alpha-D-glucosyl-[(1->6)-alpha-D-glucosyl](n) + D-fructose
Comment(s)
  • The glucansucrases transfer a D-glucosyl residue from sucrose to a glucan chain.
  • They are classified based on the linkage by which they attach the transferred residue.
  • In some cases, in which the enzyme forms more than one linkage type, classification relies on the relative proportion of the linkages that are generated.
  • This enzyme extends (1->6)-alpha-D-glucans by both alpha(1->3) and alpha(1->6) linkages, with one of the linkage types being dominant. cf. EC 2.4.1.140.
