CC   -!- FUNCTION: Hydrolyzes chitin and may play a role in defense against
CC       fungal pathogens containing chitin. {ECO:0000250|UniProtKB:Q42993,
CC       ECO:0000269|PubMed:15876312}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Random endo-hydrolysis of N-acetyl-beta-D-glucosaminide
CC         (1->4)-beta-linkages in chitin and chitodextrins.; EC=3.2.1.14;
CC         Evidence={ECO:0000269|PubMed:15876312};
CC   -!- ALLERGEN: Causes an allergic reaction in human. Binds to IgE. It
CC       exhibits some cross-reactivity with IgE antibodies from patients
CC       sensitized to latex. {ECO:0000269|PubMed:15876312}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 19 family. Chitinase
CC       class I subfamily. {ECO:0000250|UniProtKB:Q42993}.
