| Accepted name: |
dextransucrase |
| Reaction: |
sucrose + [(1→6)-α-D-glucosyl]n = D-fructose + [(1→6)-α-D-glucosyl]n+1 |
| Other name(s): |
sucrose 6-glucosyltransferase; SGE; CEP; sucrose-1,6-α-glucan glucosyltransferase; sucrose:1,6-α-D-glucan 6-α-D-glucosyltransferase |
| Systematic name: |
sucrose:(1→6)-α-D-glucan 6-α-D-glucosyltransferase |
| Comments: |
The glucansucrases transfer a D-glucosyl residue from sucrose to a glucan chain. They are classified based on the linkage by which they attach the transferred residue. In some cases, in which the enzyme forms more than one linkage type, classification relies on the relative proportion of the linkages that are generated. This enzyme extends the glucan chain by an α(1→6) linkage. |
