GO:0004565 beta-galactosidase activity

Catalysis of the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-D-galactosides.

Term Information

ID GO:0004565
Name beta-galactosidase activity
Ontology Molecular Function
Definition Catalysis of the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-D-galactosides.
Comment Note that the inclusion of 'MetaCyc:BGALACT-PWY' is exceptional: normally MetaCyc pathway entries are database references for biological process terms, not molecular function terms. An exception was made in this case because the MetaCyc entry 'BGALACT-PWY' describes only one reaction, that catalyzed by beta-galactosidase.
