| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Hydrolysis of terminal, non-reducing beta-D-mannose residues in beta-D-mannosides.; EC=3.2.1.25; |
| DNA Binding | |
| EC Number | 3.2.1.25 |
| Enzyme Function | 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 mannobiose over mannotriose and has no activity against polymeric mannan. Is also severely restricted by galactosyl substitutions at the +1 subsite (By similarity). {ECO:0000250}. |
