Chitinase is an extracellular enzyme complex that degrades chitin. It has been detected in many microorganisms and also in the digestive tracts of many animals that feed on chitin-containing organisms.
Catalog #C4154-20B
The enzymatic hydrolysis of chitin to N-acetyl-D-glucosamine is performed by two consecutive enzyme reactions. The first one, chitodextrinase-chitinase is a poly(1,4- -[2-acetamido-2-deoxy-D-glucoside])-glycanohydrolase (EC., which removes chitobiose units from chitin. The second one is N-acetyl- glucosaminidase-chitobiase, which cleaves the disaccharide to its monomer subunits, N-acetyl-D-glucosamine (NAGA). The optimal reaction temperature is 37°C.
Chitinase Activity 200 units/g solid
Protein Content 0%
Unit DefinitionOne unit will liberate 1mg of N-acetyl-D-glucosamine from chitin per hour at pH 6.0 at 25°C in a 2 hour assay.
Storage & StabilityLyophilized powder may be stored at 20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
SourceStreptomyces griseus
FormSupplied as a lyophilized powder (almost salt-free). Reconstitute with 50mM potassium phosphate, pH 6.0 yields a clear to hazy mixture.
