Glucan endo-1,3-α-glucosidase

Glucan endo-1,3-α-glucosidase (, endo-1,3-α-glucanase, mutanase, endo-(1→3)-α-glucanase, cariogenase, cariogenanase, endo-1,3-α- D -glucanase, 1,3(1,3, 1,4)-α- D -glucan 3-glucanohydrolase) is an enzyme with systematic name 3-α-D-glucan 3-glucanohydrolase. It catalyses endohydrolysis of (1→3)-α- D -glucosidic linkages in isolichenan, pseudonigeran and nigeran

Products from pseudonigeran (1,3-α- D -glucan) are nigerose and α- D -glucose.
