EC 2.4.1.30

Accepted name: 1,3-β-oligoglucan phosphorylase

Reaction: [(1→3)-β-D-glucosyl]n + phosphate = [(1→3)-β-D-glucosyl]n-1 + α-D-glucose 1-phosphate

Other name(s): β-1,3-oligoglucan:orthophosphate glucosyltransferase II; β-1,3-oligoglucan phosphorylase; 1,3-β-D-oligoglucan:phosphate α-D-glucosyltransferase

Systematic name: (1→3)-β-D-glucan:phosphate α-D-glucosyltransferase

Comments: Does not act on laminarin. Differs in specificity from EC 2.4.1.31 (laminaribiose phosphorylase) and EC 2.4.1.97 (1,3-β-D-glucan phosphorylase).
