General description
Chitinase is an extracellular complex of enzymes that degrade chitin. Chitin is a cell wall component of Fungi and exoskeketal essentials of different organisms which reshape their own chitin or digest/dissolve the chitin of other organisms (insects, fungi, yeast, and algae, and in the internal structures of other vertebrates) . Chitinases have been detected in many microorganisms and in plants. In fungi, chitinases assist in morphogenesis, to break down the inherent chitin content of fungal cell walls. Plant chitinases help in resistance to fungal attack and counteracting fungal growth, by targeting those same fungal cell walls. In bacteria, bacterial chitinases assist in utilizing chitin as a carbon source and as an energy source.Streptomyces griseus produces multiple chitinases of different molecular masses after growth induction with chitin as the carbon source.
The enzymatic hydrolysis of chitin to N-acetyl-D-glucosamine involves two consecutive enzyme reactions:
The enzymatic hydrolysis of chitin to N-acetyl-D-glucosamine involves two consecutive enzyme reactions:
- The first reaction, chitodextrinase-chitinase, is a poly(β-(1→4)-[2-acetamido-2-deoxy-D-glucoside])- glycanohydrolase, which removes chitobiose units from chitin.
- The second activity is N-acetyl-glucosaminidasechitobiase, which cleaves the disaccharide to its monomer subunits, N-acetyl-D-glucosamine.

Biochem/physiol Actions
Chitinase is an extracellular enzyme complex that degrades chitin and has a molecular mass of approximately 30 kDa. Chitin is degraded to N-acetyl-D-glucosamine in 2 enzymatic reactions. Firstly, chitobiose units are removed from chitin by chitodextrinase-chitinase. The second reaction involves N-acetyl-glucosaminidase-chitobiase, which cleaves the disaccharide to its monomer subunits (that comprise of N-acetyl-D-glucosamine). The optimum reaction temperature is 37 °C.
Features and Benefits
Chitinase is an extracellular complex of enzymes that degrade chitin. It is a lytic enzyme suitable for fungal cell walls lysis.
Unit Definition
One unit will liberate 1.0 mg of N-acetyl-D-glucosamine from chitin per hour at pH 6.0 at 25 °C in a 2 hour assay.
One new 1 hour unit = approx. 50 old 48 hour units.
