In enzymology, a 6-phospho-beta-galactosidase (EC 3.2.1.85) is an enzyme that catalyzes the chemical reaction
- a 6-phospho-beta-D-galactoside + H2O
6-phospho-D-galactose + an alcohol
Thus, the two substrates of this enzyme are 6-phospho-beta-D-galactoside and H2O, whereas its two products are 6-phospho-D-galactose and alcohol.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is 6-phospho-beta-D-galactoside 6-phosphogalactohydrolase. Other names in common use include phospho-beta-galactosidase, beta-D-phosphogalactoside galactohydrolase, phospho-beta-D-galactosidase, and 6-phospho-beta-D-galactosidase. This enzyme participates in galactose metabolism.
Structural studies
As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1PBG, 2PBG, 3PBG, and 4PBG.
