애플리케이션
Chitosanase from Sigma has been used for polarized light-stimulated, enzymatic hydrolysis of chitin and chitosan.[1]
생화학적/생리학적 작용
Chitosanase catalyzes the endohydrolysis of β-1,4-linkages between D-glucosamine (GlcN-GlcN) residues in chitosan. The enzyme from Streptomyces has been reported to also hydrolyze the GlcNAc-GlcN linkage in partially acetylated chitosan.
단위 정의
One unit will liberate 1.0 μmole of reducing sugar (measured as D-glucosamine equivalents) from chitosan per minute at pH 5.5 at 37 °C.
물리적 형태
Solution in 50% glycerol containing 50 mM sodium acetate
제조 메모
Soluble in 10mL of 0.1 M Acetate buffer at pH 5.5[1]

Canthaxanthin is a reddish-orange xanthophyll with strong antioxidant activity and higher bioavailability than carotenes, primarily used in food, cosmetics, aquaculture, and pharmaceutical industries. The spiking market for natural canthaxanthin promoted researchers toward genetic engineering of heterologous hosts for canthaxanthin production.

Chitosanase was produced by the strain of Streptomyces lividans TK24 bearing the csn gene from Streptomyces sp. N174, and purified by S-Sepharose and Bio-Gel A column chromatography. Partially (25-35%) N-acetylated chitosan was digested by the purified chitosanase, and structures of
