Comments

FUNCTION: This protein functions as a defense against chitin containing fungal pathogens.
CATALYTIC ACTIVITY: Random hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta-linkages in chitin and chitodextrins.
SUBCELLULAR LOCATION: Secreted, cell wall.
INDUCTION: By TMV infection.
SIMILARITY: Belongs to the glycosyl hydrolase 18 family. Chitinase class II subfamily [view classification].
