Purification and hydrolytic action of a chitosanase from Nocardia orientalis

Autor: Katsumi Ryosuke, Ayako Isobe, Kazuo Sakai, Fumio Nanjo

Publikováno v: Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology. 1079:65-72

Chitosanase from the culture filtrate of Nocardia orientalis was purified to apparent homogeneity by precipitation with ammonium sulfate followed by CM-Sephadex chromatography, biospecific affinity chromatography on a Sepharose CL-4B with immobilized

Publikováno v: Agricultural and Biological Chemistry. 54:899-906

β-N-Acetylhexosaminidase (EC 3.2.1.52) from the culture filtrate of Nocardia orientalis was purified to homogeneity by precipitation with ammonium sulfate followed by column chromatography on CM-Sephadex, Bio-Gel P-60, and phenyl-Sepharose CL-4B. Th

Enzymatic method for determination of the degree of deacetylation of chitosan

Autor: Katsumi Ryosuke, Fumio Nanjo, Kazuo Sakai

Publikováno v: Analytical biochemistry. 193(2)

A new method was developed for the accurate determination of the degree of deacetylation of chitosan. The method involves the complete hydrolysis of chitosan to glucosamine and N-acetylglucosamine by a cooperative action of chitosanolytic enzymes exo
