Enzyme Information

Chitinase.
based on mapping to UniProt Q9BZP6
Random endo-hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta- linkages in chitin and chitodextrins.
-!- The enzyme binds to chitin and randomly cleaves glycosidic linkages in chitin and chitodextrins in a non-processive mode, generating chitooligosaccharides and free ends on which exo-chitinases and exo- chitodextrinases can act. -!- Activity is greatly stimulated in the presence of EC 1.14.99.53, which attacks the crystalline structure of chitin and makes the polymer more accesible to the chitinase. -!- Cf. EC 3.2.1.202.
