Project description:AdpA is a global transcriptional activator triggering morphological differentiation and secondary metabolism in Streptomyces griseus. AdpA influences expression of >1,000 genes, but the overall picture of AdpA regulon has been obscure. Here, we took snapshots of distribution of AdpA across the chromosome in living S. griseus cells by ChIP/ChAP-seq analysis. In both liquid and solid cultures, AdpA bound to similar >1,200 sites, which were located on not only putative regulatory regions (65 %) but also regions (35 %) that appeared not to affect transcription. Transcriptome analysis indicated that approximately 40% of the AdpA binding sites in putative regulatory regions were involved in gene regulation. AdpA was indicated to act as a transcriptional repressor as well as an activator. Expression profiles of AdpA-target genes were very different between liquid and solid cultures in spite of similar AdpA-binding profiles. We therefore concluded that AdpA directly controls >500 genes in cooperation with other regulatory proteins in many cases. In vitro AdpA binding to the selected 304 AdpA-binding sites was examined, revealing several unique characteristics of AdpA regarding its DNA-binding property. This study gave the first experimental insight into the extent of AdpA regulon, indicating many genes under the direct control of AdpA.

Project description:The RNA sequencing approach was utilized to carry out a comparative transcriptome analysis between Streptomyces hygroscopicus 5008 wild-type and a genetically engineered strain. The A-factor-like cascade play an important role in the regulation of validamycin biosynthesis by Streptomyces hygroscopicus 5008, and the pleiotropic regulator AdpA-H may positively regulate the transcription of gene cluster for the biosynthesis. shbR1 and shbR3 as the A-factor receptor homolog genes, could repress the transcription of AdpA-H. By tandem deletions of these genes, the production and productivity of validamcyin was significantly enhanced. To explore the effects of the shbR1/R3 double deletion of the overall cellular metabolism, the RNA sequencing approach was utilized to carry out a comparative transcriptome analysis between wild-type and shbR1/shbR3 double mutant (genetically engineered strain).
