l  生物学信息

生物活性/药理作用

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.

应 用

Chitinase from Streptomyces griseus has been used to study the effect of the allosamidin on the regulatory system for chitinase production. It has also been used to study the enrichment of chitinolytic microorganisms. This enrichment was achieved by the isolation and characterization of a chitinase with antifungal activity against  phytopathogenic fungi. Chitinase from Streptomyces griseus has been used as a standard for chitinase assays using the enzyme derived from Absidia glauca and Petunia hybrida extracts.

有效单位定义

One unit will liberate 1.0mg of N-acetyl-D-glucosamine from chitin per hour at pH6.0 at 25°C in a 2 hour assay.

One new 1hour unit = approx. 50 old 48 hour units.
