CC   -!- FUNCTION: Defense against chitin containing fungal and bacterial
CC       pathogens.
CC   -!- CATALYTIC ACTIVITY: Random hydrolysis of N-acetyl-beta-D-
CC       glucosaminide (1->4)-beta-linkages in chitin and chitodextrins.
CC   -!- INDUCTION: Constitutively expressed at low levels.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 19 family. Chitinase
CC       class I subfamily.
