Project description:RNA seq analysis was performed using adpA-deleted and adpA-overexpressed Streptomyces clavuligerus strains to determine its regulatory effect on tunicamycin and other secondary metabolites production
Project description:The objective is to analyze the differential expression between the wild strain and a ccaR-deleted and oppA2::aph mutants 6 biological conditions were used, three strains in two times (exponential and stationary growth phase; Streptomyces clavuligerus ATCC 27064, S. clavuligerus M-bM-^HM-^FccaR and S. clavuligerus oppA2::aph). Four biological replicates were made for each condition
Project description:This SuperSeries is composed of the following subset Series: GSE33992: Streptomyces griseus transcriptome analysis in solid culture with delta adpA, encoding a global transcriptional regulator involved in morphological differentiation and secondary metabolism GSE33993: Streptomyces griseus transcriptome analysis in liquid culture with delta adpA, encoding a global transcriptional regulator involved in morphological differentiation and secondary metabolism GSE34036: Genome-wide distribution of AdpA, a global regulator for secondary metabolism and morphological differentiation in Streptomyces [liquid] GSE34037: Genome-wide distribution of AdpA, a global regulator for secondary metabolism and morphological differentiation in Streptomyces [solid] Refer to individual Series
Project description:The objective is to analyze the expression level of a Streptomyces clavuligerus oppA2-deleted mutant Experiment type Expression profiling by array
Project description:The objective was to analyze the differential expression between the wild strain and the Streptomyces clavuligerus ΔclaR::aac mutant Six experimental conditions were assayed, two strains (Streptomyces clavuligerus ATCC 27064, S. clavuligerus ΔclaR::aac) in three culture times (22.5h, 46.5h and 60 h). Two biological replicates for each condition.
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.
