Protein

Beta-mannosidase B

Gene

mndB

Organism
Aspergillus oryzae (strain ATCC 42149 / RIB 40) (Yellow koji mold)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

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).By similarity

Catalytic activityi

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