IntEnz Enzyme Nomenclature
EC 2.4.1.321

Names

Accepted name:
cellobionic acid phosphorylase
Systematic name:
4-O-β-D-glucopyranosyl-D-gluconate:phosphate α-D-glucosyltransferase

Reaction

Comments:

The enzyme occurs in cellulolytic bacteria and fungi. It catalyses the reversible phosphorolysis of cellobionic acid. In the synthetic direction it produces 4-O-β-D-glucopyranosyl-D-glucuronate from α-D-glucose 1-phosphate and D-glucuronate with low activity.
