Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Exoglycosidase that cleaves the single beta-linked mannose residue from the non-reducing end of beta-mannosidic oligosaccharides of various complexity and length. Prefers manobiose over mannotriose and has no activity against polymeric mannan. Is also severly restricetd by galactosyl substitutions at the +1 subsite By similarity.

Catalytic activity

Hydrolysis of terminal, non-reducing beta-D-mannose residues in beta-D-mannosides.

Pathway

Glycan metabolism; N-glycan degradation.

Miscellaneous

In contrast to clade A beta-mannosidases, which are likely secreted, clade B proteins appear to be intracellular By similarity.

Sequence similarities

Belongs to the glycosyl hydrolase 2 family. Beta-mannosidase B subfamily.
