Glucan 1,3-α-glucosidase

Glucan 1,3-α-glucosidase (, exo-1,3-α-glucanase, glucosidase II, 1,3-α- D -glucan 3-glucohydrolase) is an enzyme with systematic name 3-α- D -glucan 3-glucohydrolase. It catalyses the hydrolysis of terminal (1→3)-α- D -glucosidic links in (1→3)-α- D -glucans.

It does not act on nigeran although it has some activity against nigerose.
