Involved in the dissolution of the mother-daughter septum during cell separation. Endohydrolysis of (1->3)- or (1->4)-linkages in beta-D-glucans when the glucose residue whose reducing group is involved in the linkage to be hydrolyzed is itself substituted at C-3. Localizes asymmetrically to the daughter side of the septum. Glycosylated. Present with 64 molecules/cell in log phase SD medium. Belongs to the glycosyl hydrolase 81 family.
