Mycodextranase (, 1,3-1,4-ñ-<small>D</small>-glucan 4-glucanohydrolase) is an enzyme with systematic name (1âÂÂ3)-(1âÂÂ4)-ñ-<small>D</small>-glucan 4-glucanohydrolase. It catalyses endohydrolysis of (1âÂÂ4)-ñ-<small>D</small>-glucosidic linkages in ñ-<small>D</small>-glucans containing both (1âÂÂ3)- and (1âÂÂ4)-bonds
Products are nigerose and 4-ñ-<small>D</small>-nigerosylglucose.
