Cloning of a Gene Cluster from Cellvibrio mixtus which Codes for Cellulase, Chitinase, Amylase, and Pectinase

By E. C. Wynne and J. M. Pemberton


The soil isolate Cellvibrio mixtus UQM2294 degraded a variety of polysaccharides including microcrystalline cellulose. Among 6,000 cosmid clones carrying C. mixtus DNA, constructed in Escherichia coli with pHC79, 50 expressed the ability to degrade one or more of the following substrates: carboxymethyl cellulose, chitin, pectin (polygalacturonic acid), cellobiose, and starch. These degradative genes are encoded in a single 94.1-kilobase segment of the C. mixtus genome; a preliminary order of the genes is starch hydrolysis, esculin hydrolysis, cellobiose utilization, chitin hydrolysis, carboxymethyl cellulose hydrolysis, and polygalacturonic acid hydrolysis. A restriction endonuclease cleavage map was constructed, and the genes for starch, carboxymethyl cellulose, cellobiose, chitin, and pectin hydrolysis were subcloned
