Comments

FUNCTION: Able to cleave chitin oligomers from N=3 to 6.
CATALYTIC ACTIVITY: Random hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta-linkages in chitin and chitodextrins.
SUBUNIT: Homodimer, but homotrimers and homotetramers could be observed for the 20.5 and 30 kDa chitinases.
PTM: The 70 kDa chitinase is probably the precursor protein of the 30 and 20.5 kDa chitinases.
SIMILARITY: Belongs to the glycosyl hydrolase 18 family. Chitinase class II subfamily [view classification].
