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}. |
