2.4.1.231 |
| Accepted name: |
α,α-trehalose phosphorylase (configuration-retaining) |
| Reaction: |
α,α-trehalose + phosphate = α-D-glucose + α-D-glucose 1-phosphate |

| Other name(s): |
trehalose phosphorylase[ambiguous] |
| Systematic name: |
α,α-trehalose:phosphate α-D-glucosyltransferase |
| Comments: |
Unlike EC 2.4.1.64, α,α-trehalose phosphorylase, this enzyme retains its anomeric configuration. Vanadate is a strong competitive inhibitor of this reversible reaction. |
