Comments

FUNCTION: Probably involved in the apical growth and branching of fungal hyphae.
CATALYTIC ACTIVITY: Random hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta-linkages in chitin and chitodextrins.
SUBUNIT: Monomer.
SUBCELLULAR LOCATION: Secreted (Probable).
PTM: O-glycosylated.
SIMILARITY: Belongs to the glycosyl hydrolase 18 family. Chitinase class II subfamily [view classification].
