Chitinase
Chitinase (barley seed chitinase:
PDB 1CNS, EC 3.2.1.14) is a digestive
enzyme that breaks down glycosidic bonds in
chitin. It is found in chitinivorous
bacteria (bacteria that are able to digest chitin), and if the entries in the
Protein Data Bank are correct, quite a few plants have chitinases as well.
