A	licheninase (glycosyl hydrolase 17 family) M-CSA #400	Functions in plant cell wall hydrolysis ((1->4)-beta-D-glucosidic linkages in beta-D-glucans containing (1->3)- and (1->4)-bonds) during mobilization of the endosperm in germinating grain or during the growth of vegetative tissues. This protein is involved in the pathway beta-D-glucan degradation, which is part of Glycan metabolism.
