IntEnz Enzyme Nomenclature
EC 3.2.1.77

Names

Accepted name:
mannan 1,2-(1,3)-α-mannosidase
Other names:
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

Reaction

Comments:

A 1,6-α-D-mannan backbone remains after action on yeast mannan. This is further attacked, but slowly.
