Sysname
3-beta-D-glucosyl-D-glucose:phosphate alpha-D-glucosyltransferase
Reaction(IUBMB)
3-beta-D-glucosyl-D-glucose + phosphate = D-glucose + alpha-D-glucose 1-phosphate [RN:R00953 R06058]
Reaction(KEGG)
R00953 R06058(G)
Substrate
3-beta-D-glucosyl-D-glucose [CPD:C02048];
phosphate [CPD:C00009]
Product
D-glucose [CPD:C00031];
alpha-D-glucose 1-phosphate [CPD:C00103]
Comment
Also acts on 1,3-beta-D-oligoglucans. Differs in specificity from EC 2.4.1.30 (1,3-beta-oligoglucan phosphorylase) and EC 2.4.1.97 (1,3-beta-D-glucan phosphorylase).
