Identification and characterization of the actinomycin G gene cluster in Streptomyces iakyrus
Abstract
The gene cluster directing actinomycin G biosynthesis in Streptomyces iakyrus has been identified and sequenced. It contains one actinomycin synthetase I (ACMS I) gene and two copies of ACMS II and III genes. Genetic analysis demonstrates a unique partnership between the putative hydroxylation and chlorination activities as both acmG8 and acmG9 genes need to be transcribed for the biosynthesis of actinomycin G2-3, respectively.
