Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
BRITE hierarchy
Sysname
1,2-beta-D-glucan:phosphate alpha-D-glucosyltransferase
Reaction(IUBMB)
[(1->2)-beta-D-glucosyl]n + phosphate = [(1->2)-beta-D-glucosyl]n-1 + alpha-D-glucose 1-phosphate
Reaction(KEGG)
(other) R11128
Show
Substrate
[(1->2)-beta-D-glucosyl]n [CPD:C02490];
phosphate [CPD:C00009]
Product
[(1->2)-beta-D-glucosyl]n-1;
alpha-D-glucose 1-phosphate [CPD:C00103]
Comment
The enzyme has been isolated from the bacterium Listeria innocua. It catalyses the reversible phosphorolysis of beta-(1->2)-D-glucans. The minimum length of the substrate for the phosphorolytic reaction is 3 D-glucose units. In the synthetic reaction starting from sophorose and alpha-D-glucose 1-phosphate the average polymerisation degree is 39.
