설명

애플리케이션

Chitosanase from Sigma has been used for polarized light-stimulated, enzymatic hydrolysis of chitin and chitosan.

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
