6-phospho-β-galactosidase

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

a 6-phospho-β-<small>D</small>-galactoside + H<sub>2</sub>O 6-phospho-<small>D</small>-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-<small>D</small>-galactoside 6-phosphogalactohydrolase. Other names in common use include phospho-β-galactosidase, β-<small>D</small>-phosphogalactoside galactohydrolase, phospho-β-<small>D</small>-galactosidase, and 6-phospho-β-<small>D</small>-galactosidase. This enzyme participates in galactose metabolism.
