Purification and properties of a thermostable chitinase from Streptomyces thermoviolaceus OPC-520.

Osaka University of Pharmaceutical Sciences, Japan.

ABSTRACT

A chitinase was purified from the culture filtrate of Streptomyces thermoviolaceus OPC-520. The enzyme showed a high optimum temperature (70 to 80 degrees C), a high optimum pH level (8.0 to 10.0), and heat stability. This enzyme showed high sequence homology with chitinases from Serratia marcescens QMB1466 and Bacillus circulans WL-12.
