title: Cloning and expression of a Streptomyces cholesterol oxidase gene in Streptomyces lividans with plasmid pIJ702.
abstract: The cholesterol oxidase gene (cho) of Streptomyces sp. was cloned into Streptomyces lividans with the vector pIJ702. Deletion analysis of the recombinant plasmid showed that entire coding sequence of the cho gene was located within a 2.5-kilobase segment of the chromosomal DNA obtained from the cholesterol oxidase-producing strain. When cloned cells of S. lividans were grown in an appropriate medium, the cells produced severalfold more cholesterol oxidase extracellularly than did the producing strain.
