Accepted name: |
mannan 1,2-(1,3)-α-mannosidase |
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. |
