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.
Structural studies
As of 2007, four structures have been solved for this class of enzymes, with PDB accession codes 1PBG, 2PBG, 3PBG, and 4PBG.
