Identification by ChIP-Seq of the binding sites of the developmental protein WhiH in the genome of Streptomyces venezuelae
The whiH gene is required for the differentiation of aerial hyphae into spores in Streptomyces species. It is a predicted member of the GntR family of transcription factors and has been shown to bind specifically to a sequence in its own promoter. This ChIP-Seq experiment was carried out to determine all the binding sites whiH binds to in the genome of Streptomyces venezuelae. A whiH deletion strain was made and a FLAG tagged whiH protein was expressed in it from a genome-integrated plasmid. Then anti-FLAG antibodies were used for chromatin immunoprecipitation followed by high throughput sequencing. The wild type Streptomyces venezuelae strain (ATCC 10712) was used as a negative control. For both the FLAG-WhiH strain and the WT strain, non-immunoprecipitated (total) DNA was also sequenced to arrive at a background enrichment which could be subtracted from the enrichment in the immunoprecipated sample.
