Study on Enzymatic Characteristics of Chitin Deacetylase

Abstract:

Chitin deacetylase (CDA) catalyzes the conversion of chitin to chitosan by the deacetylation of N-acetyl-D-glucosamine residues. The results of the fundamental enzymatic properties of chitin deacetylase producing from the high productivity chitin deacetylase strain Z7 show that, the optimum temperature of strain Z7 was 40°C, the optimum pH was 6.5, under the concentration of 1mmol/L, Mg²⁺, K⁺, Ca²⁺ and Fe²⁺ had activation effect, of which the strongest activation effect was Mg²⁺. Pb²⁺, Cu²⁺ and Mn²⁺ had inhibitory effect, of which the strongest inhibitory effect was Mn²⁺.
