title: Conserved organization of genes for biosynthesis of chlortetracycline in Streptomyces strains.
abstract: By genomic Southern blot analysis, the DNA sequences homologous to the gene cluster responsible for biosynthesis of 6-demethyl-chlortetracycline in Streptomyces aureofaciens NRRL3203 were shown to be highly conserved in independent chlortetracycline- or tetracycline producing Streptomyces strains. By contrast, oxytetracycline-producing Streptomyces strains had no hybridization with the cluster DNA.
