Abstract Streptomyces castaneoglobisporus HUT6202 overproduces a diffusible melanin pigment and harbors a cryptic 7.4‐kb plasmid, pHY6202. We constructed a Streptomyces cloning vector, pSY10CMM, consisting of the HUT6202 rep gene, the thiostrepton resistance gene and an operon encoding the synthesis of melanin pigment, abbreviated mel , from S. castaneoglobisporus . The vector, which has Sph I and Bam HI sites as cloning sites with insertional inactivation of the mel , is a more convenient cloning vector than commonly used pIJ702, because of its broad host range for antibiotic‐producing Streptomyces strains and its much greater production of diffusible melanin pigment.
