| Accepted name: |
N,N′-diacetylchitobiose phosphorylase |
| Reaction: |
N,N′-diacetylchitobiose + phosphate = N-acetyl-D-glucosamine + N-acetyl-α-D-glucosamine 1-phosphate |
| Glossary: |
N,N′-diacetylchitobiose = N-acetyl-D-glucosaminyl-β-(1→4)-N-acetyl-D-glucosamine |
| Other name(s): |
chbP (gene name) |
| Systematic name: |
N,N′-diacetylchitobiose:phosphate N-acetyl-D-glucosaminyltransferase |
| Comments: |
The enzyme is specific for N,N′-diacetylchitobiose and does not phosphorylate other N-acetylchitooligosaccharides, cellobiose, trehalose, lactose, maltose or sucrose. |
