ENZYME entry: EC 2.4.1.125
Accepted Name |
Sucrose--1,6-alpha-glucan 3(6)-alpha-glucosyltransferase.
|
Alternative Name(s) |
Water-soluble-glucan synthase. |
Reaction catalysed |
- Sucrose + ((1->6)-alpha-D-glucosyl)(n) <=> D-fructose + ((1->6)-alpha-D-glucosyl)(n+1)
- Sucrose + ((1->6)-alpha-D-glucosyl)(n) <=> D-fructose + (1->3)-alpha-D-glucosyl-((1->6)-alpha-D-glucosyl)(n)
|
Comment(s) |
- 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 (1->6)-alpha-D-glucans by both alpha(1->3) and
alpha(1->6) linkages, with one of the linkage types being dominant.
- Cf. EC 2.4.1.140.
