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 BCR1 and FKH2. Transcription is greater during growth of the yeast form as compared to the mycelial form, and down-regulated by micafungin treatment. The GPI-anchor is attached to the protein in the endoplasmic reticulum and serves to target the protein to the cell surface. There, the glucosamine-inositol phospholipid moiety is cleaved off and the GPI-modified mannoprotein is covalently attached via its lipidless GPI glycan remnant to the 1,6-beta-glucan of the outer cell wall layer. Proteolytic cleavage by SAP9 and SAP10 leads to the cell wall release of CHT2 and increased chitinase activity, suggesting a direct influence of SAP9 and SAP10 on CHT2 function. Leads to the clumping or clusterings of cells from early exponential phase, and to increased hyphal growth on solid media. Belongs to the glycosyl hydrolase 18 family. Chitinase class III subfamily.
