| Accepted name: |
cellobionic acid phosphorylase |
| Reaction: |
4-O-β-D-glucopyranosyl-D-gluconate + phosphate = α-D-glucose 1-phosphate + D-gluconate |
| Glossary: |
4-O-β-D-glucopyranosyl-D-gluconate = cellobionate |
| Systematic name: |
4-O-β-D-glucopyranosyl-D-gluconate:phosphate α-D-glucosyltransferase |
| 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 |
