Molecular function

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

beta-D-galactanase activity, beta-D-galactoside galactohydrolase activity, beta-D-lactosidase activity, beta-lactosidase activity, exo-(1->4)-beta-D-galactanase activity, hydrolact

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.
