Chitinase and Chitin

Synonyms: 1,4-ß-poly-N-acetylglucosaminidase
Chitinases are enzymes that catalyze the degradation of chitin. They have been detected in many organisms, including bacteria, fungi, plants, invertebrates and vertebrates.1,2 Chitinases are broadly classified as endo- and exochitinases. The endochitinase activity is defined as the random cleavage at internal points in the chitin chain. The exochitinase activity is defined as the progressive action starting at the non-reducing end of chitin with the release of chitobiose or N-acetylglucosamine units.2,3 Chitobiosidase and N-acetyl-b-glucosaminidase are considered exochitinases.2 The combination of endo- and exochitinases results in a synergistic increase in the chitinolytic activity.4
