Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

A 6-phospho-beta-D-galactoside + H2O = 6-phospho-D-galactose + an alcohol. HAMAP-Rule MF_01574

Pathway

Carbohydrate metabolism; lactose degradation; D-galactose 6-phosphate and beta-D-glucose from lactose 6-phosphate: step 1/1. HAMAP-Rule MF_01574

Sequence similarities

Belongs to the glycosyl hydrolase 1 family.

Sequence caution

The sequence ABF38679.1 differs from that shown. Reason: Erroneous initiation.
