KEGG ENZYME: 2.4.1.372

Entry
EC 2.4.1.372                Enzyme                                 
Name

mutansucrase;
gtfJ (gene name)

Class

Transferases;
Glycosyltransferases;
Hexosyltransferases

Sysname

sucrose:(1->3)-alpha-D-glucan 3-alpha-D-glucosyltransferase

Reaction(IUBMB)
sucrose + [(1->3)-alpha-D-glucosyl]n = D-fructose + [(1->3)-alpha-D-glucosyl]n+1 [RN:R12527]
Reaction(KEGG) Substrate
sucrose [CPD:C00089];
[(1->3)-alpha-D-glucosyl]n [CPD:C02616]
Product
D-fructose [CPD:C00095];
[(1->3)-alpha-D-glucosyl]n+1
Comment

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 alpha(1->3) linkage.
