KEGG   ENZYME: 2.4.1.5
Entry
EC 2.4.1.5                  Enzyme                                 
Name
dextransucrase;
sucrose 6-glucosyltransferase;
SGE;
CEP;
sucrose-1,6-alpha-glucan glucosyltransferase;
sucrose:1,6-alpha-D-glucan 6-alpha-D-glucosyltransferase
Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
Sysname
sucrose:(1->6)-alpha-D-glucan 6-alpha-D-glucosyltransferase
Reaction(IUBMB)
sucrose + [(1->6)-alpha-D-glucosyl]n = D-fructose + [(1->6)-alpha-D-glucosyl]n+1 [RN:R02120 R06066]
Reaction(KEGG)
R02120 R06066(G)
Substrate
sucrose [CPD:C00089];
[(1->6)-alpha-D-glucosyl]n
Product
D-fructose [CPD:C00095];
[(1->6)-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->6) linkage.
