Application
Chitosanase from Sigma has been used for polarized light-stimulated, enzymatic hydrolysis of chitin and chitosan.[1]
Biochem/physiol Actions
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.
Unit Definition
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.
Physical form
Solution in 50% glycerol containing 50 mM sodium acetate
Preparation Note
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.
