dc.description.abstractAnalysis of the simocyclinone biosynthesis (sim) gene cluster of Streptomyces antibioticus Tü6040 led to the identification of a putative pathway specific regulatory gene simReg1. In silico analysis places the SimReg1 protein in the OmpR-PhoB subfamily of response regulators. Gene replacement of simReg1 from the S. antibioticus chromosome completely abolishes simocyclinone production indicating that SimReg1 is a key regulator of simocyclinone biosynthesis. Results of the DNA-shift assays and reporter gene expression analysis are consistent with the idea that SimReg1 activates transcription of simocyclinone biosynthesis, transporter genes, regulatory gene simReg3 and his own transcription. The presence of extracts (simocyclinone) from S. antibioticus Tü6040 × pSSimR1-1 could dissociate SimReg1 from promoter regions. A preliminary model for regulation of simocyclinone biosynthesis and export is discussed.
