6-phospho-β-galactosidase

The enzyme 6-phospho-β-galactosidase catalyzes the following reaction:


 * a 6-phospho-β- D -galactoside + H2O $$\rightleftharpoons$$ 6-phospho- D -galactose + an alcohol

This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name is 6-phospho-β- D -galactoside 6-phosphogalactohydrolase. Other names in common use include phospho-β-galactosidase, β- D -phosphogalactoside galactohydrolase, phospho-β- D -galactosidase, and 6-phospho-β- D -galactosidase. This enzyme participates in galactose metabolism.
