FIG. 3.
Expression of Rv0095c and ctpB is regulated by σC. (A) Genome-wide enrichment of σC by ChIP. The asterisks indicate target genes validated by qPCR. (B) ChIP qPCR validation for the region upstream of Rv0095c and ctpB. (C) Detected transcription start sites and putative σC recognized boxes. Transcription start sites are indicated by boldface uppercase letters, and proposed promoter boxes are underlined. (D) In vitro transcription using the 13 M. tuberculosis σ factors in the ctpB upstream region.
