Endo-1,3(4)-beta-glucanase involved in the cell separation process. Plays no essential role in growth, nor is it involved in hyphal morphogenesis. 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. Expression is decreased during the hyphal transition, in biofilm, as well as by heat stress, caspofungin, fluconazole, and alpha pheromone. Transcription is also regulated by ACE2 and SIT4. Leads to clusters of growing cells that have not completed separation. Belongs to the glycosyl hydrolase 81 family.
