Reaction: Hydrolysis of (1→2)- and (1→3)-linkages in yeast mannan, releasing mannose
Other name(s): exo-1,2-1,3-α-mannosidase; 1,2-1,3-α-D-mannan mannohydrolase
Systematic name: (1→2)-(1→3)-α-D-mannan mannohydrolase
Comments: A 1,6-α-D-mannan backbone remains after action on yeast mannan. This is further attacked, but slowly.
