Chitinase involved in the remodeling of chitin in the fungal cell wall. Plays a role in cell separation. Random endo-hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta-linkages in chitin and chitodextrins. Expression is positively regulated by ACE2. Transcription is greater during growth of the yeast form as compared to the mycelial form, and down-regulated by micafungin treatment. Leads to strong decrease of secreted chitinase activity, as well as to the clumping or clusterings of cells from early exponential phase. Belongs to the glycosyl hydrolase 18 family. Chitinase class III subfamily.
