Accepted name: mannan exo-1,2-1,6-α-mannosidase

Reaction: Hydrolysis of (1→2)-α-D- and (1→6)-α-D- linkages in yeast mannan, releasing D-mannose

Other name(s): exo-1,2-1,6-α-mannosidase

Systematic name: (1→2)-(1→6)-α-D-mannan D-mannohydrolase

Comments: Mannose residues linked α-D-1,3- are also released, but very slowly.
