ENZYME entry: EC 3.2.1.197

Accepted Name
beta-1,2-mannosidase.
Reaction catalysed
beta-D-Manp-(1->2)-beta-D-Manp-(1->2)-D-Manp + H2O <=> alpha-D-mannopyranose + beta-D-mannopyranosyl-(1->2)-D-mannopyranose
Comment(s)
  • The enzyme, characterized from multiple bacterial species, catalyzes the hydrolysis of terminal, non-reducing D-mannose residues from beta-1,2-mannotriose and beta-1,2-mannobiose.
  • The mechanism involves anomeric inversion, resulting in the release of alpha-D-mannopyranose.
  • Activity with beta-1,2-mannotriose or higher oligosaccharides is higher than that with beta-1,2-mannobiose.
