GO
GO:0009341 A protein complex that possesses beta-galactosidase activity, i.e. catalyzes the hydrolysis of terminal non-reducing beta-D-galactose residues in beta-D-galactosides. In E. coli, the complex is a homotetramer; dimeric and hexameric beta-galactosidase complexes have been observed in other species. GO:0005975 The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. GO:0004565 Catalysis of the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-D-galactosides. GO:0046872 Binding to a metal ion.
