Mannan 1,2-(1,3)-a-mannosidase
Mannan 1,2-(1,3)-alpha-mannosidase (EC 3.2.1.77, exo-1,2-1,3-alpha-mannosidase, 1,2-1,3-alpha-D-mannan mannohydrolase) is an enzyme with systematic name (1->2)-(1->3)-alpha-D-mannan mannohydrolase.[1][2] This enzyme catalyses the following chemical reaction
- Hydrolysis of (1->2)- and (1->3)-linkages in yeast mannan, releasing mannose
