5.4.99.11 |
| Accepted name: |
isomaltulose synthase |
| Reaction: |
sucrose = 6-O-α-D-glucopyranosyl-D-fructofuranose |
| Other name(s): |
isomaltulose synthetase; sucrose α-glucosyltransferase; trehalulose synthase |
| Systematic name: |
sucrose glucosylmutase |
| Comments: |
The enzyme simultaneously produces isomaltulose (6-O-α-D-glucopyranosyl-D-fructose) and smaller amounts of trehalulose (1-O-α-D-glucopyranosyl-β-D-fructose) from sucrose. |
