Enzyme Information

3.2.1.23
Beta-galactosidase.
based on mapping to UniProt Q8VNN2
Hydrolysis of terminal non-reducing beta-D-galactose residues in beta-D- galactosides.
-!- Some enzymes in this group hydrolyze alpha-L-arabinosides; some animal enzymes also hydrolyze beta-D-fucosides and beta-D-glucosides (cf. EC 3.2.1.108).
