Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
BRITE hierarchy
Sysname
4-O-beta-D-glucopyranosyl-D-gluconate:phosphate alpha-D-glucosyltransferase
Reaction(IUBMB)
4-O-beta-D-glucopyranosyl-D-gluconate + phosphate = alpha-D-glucose 1-phosphate + D-gluconate [RN:R10832]
Reaction(KEGG)
Substrate
4-O-beta-D-glucopyranosyl-D-gluconate [CPD:C20888];
phosphate [CPD:C00009]
Product
alpha-D-glucose 1-phosphate [CPD:C00103];
D-gluconate [CPD:C00257]
Comment
The enzyme occurs in cellulolytic bacteria and fungi. It catalyses the reversible phosphorolysis of cellobionic acid. In the synthetic direction it produces 4-O-beta-D-glucopyranosyl-D-glucuronate from alpha-D-glucose 1-phosphate and D-glucuronate with low activity
