General annotation (Comments)

Function

Involved in cell wall degradation. Degrades polysaccharides containing beta-(1-->4)-linked galactans, acting as an exo-(1-->4)-beta-D-galactanase By similarity. UniProtKB P48981

Catalytic activity

Hydrolysis of terminal non-reducing beta-D-galactose residues in beta-D-galactosides. UniProtKB P48981

Subunit structure

Heterodimer of a large and a small subunit. Ref.1

Post-translational modification

The small subunit is N-glycosylated. Ref.1

Miscellaneous

There are three forms of the large subunit which have the same sequence but differ in charge. There are four forms of the small subunit which have the same sequence but differ in charge. Ref.1

Sequence similarities

Belongs to the glycosyl hydrolase 35 family.
