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   -!- TISSUE SPECIFICITY: Expressed at low levels in roots, leaves and
CC       meristems. {ECO:0000269|PubMed:16936841}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 19 family. Chitinase
CC       class I subfamily. {ECO:0000305}.
CC   -!- CAUTION: Lacks the chitin binding type-1 domain wich is one of the
CC       conserved features of the chitinase class I and class IV subfamilies.
CC       {ECO:0000305}.
