A	PF02449	Beta-galactosidase (Glyco_hydro_42)	Beta-galactosidase	This group of beta-galactosidase enzymes belong to the glycosyl hydrolase 42 family. The enzyme catalyses the hydrolysis of terminal, non-reducing terminal beta-D-galactosidase residues.	Domain
A	PF08532	Beta-galactosidase trimerisation domain (Glyco_hydro_42M)	Beta-galactosidase trimerisation domain	This is non catalytic domain B of beta-galactosidase enzymes belong to the glycosyl hydrolase 42 family. This domain is related to glutamine amidotransferase enzymes, but the catalytic residues are replaced by non functional amino acids. This domain ...	This is non catalytic domain B of beta-galactosidase enzymes belong to the glycosyl hydrolase 42 family. This domain is related to glutamine amidotransferase enzymes, but the catalytic residues are replaced by non functional amino acids. This domain is involved in trimerisation [1].	Domain
A	PF08533	Beta-galactosidase C-terminal domain (Glyco_hydro_42C)	Beta-galactosidase C-terminal domain	This domain is found at the C-terminus of beta-galactosidase enzymes that belong to the glycosyl hydrolase 42 family [1].	Domain
