OX NCBI_TaxID=10116; RN [1] RP SEQUENCE FROM N.A. RC STRAIN=Sprague-Dawley; TISSUE=Stomach; RA Chen X.-H., Cai G.-P.; RT "Rattus norvegicus similar to acidic mammalian chitinase precursor."; RL Submitted (NOV-2003) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Degrades chitin and chitotriose. May participate in the CC defense against nematodes and other pathogens (By similarity). CC -!- CATALYTIC ACTIVITY: Hydrolysis of the 1,4-beta-linkages of N- CC acetyl-D-glucosamine polymers of chitin. CC -!- SUBCELLULAR LOCATION: Secreted (By similarity). CC -!- SIMILARITY: Belongs to family 18 of glycosyl hydrolases. Chitinase CC class II subfamily. CC -!- SIMILARITY: Contains 1 chitin-binding type-2 domain.
