Inactive chitinase-like protein that does not exhibit hydrolytic activity toward chitin (PubMed:25104038). Binds strongly to chitin and possesses antifungal activity toward the fungal pathogen Altenaria alternata in plate assays (PubMed:25104038). Probably involved in defense against fungal pathogens through a mechanism that only involves carbohydrate binding (PubMed:25104038). May cause an allergic reaction in human (By similarity). Binds to IgE from sera of patients allergic to rubber latex (By similarity). Belongs to the glycosyl hydrolase 19 family. Chitinase class I subfamily. Lacks the conserved Glu active site in position 166, which is replaced by an Ala residue, explaining why it is inactive.
