General annotation (Comments)

Function

Hydrolyzes cellobiose 6'-phosphate into glucose 6-phosphate (Glc6P) and glucose.

Catalytic activity

6-phospho-beta-D-glucosyl-(1,4)-D-glucose + H2O = D-glucose + D-glucose 6-phosphate.

Cofactor

Binds 1 NAD per subunit.

Binds 1 manganese ion per subunit.

Subunit structure

Homodimer or homotetramer. Exists in a homodimer/homotetramer equilibrium state in solution.

Miscellaneous

Is a retaining glucosidase as it hydrolyzes glycosidic bond with retention of anomeric configuration. Reaction mechanism includes redox steps involving NAD and stabilization of intermediates by Mn2+.

Sequence similarities

Belongs to the glycosyl hydrolase 4 family.

Biophysicochemical properties

Kinetic parameters:

KM=41 µM for p-nitrophenyl-beta-D-glucopyranoside 6-phosphate

pH dependence:

Optimum pH is 8.0. Active from pH 6.5 to 10.
