Transcriptional regulation by the position of uncharacterized TFs relative to the binding of RNA polymerase (RNAP), using binding sites from YeiE, YieP, YiaJ, and YafC as representatives. (A) In the case of dcuC, YeiE-binding is located downstream of the promoter. (B) YeiE binds to the upstream site of the yoaC. (C) YeiE-binding region upstream of serC overlaps with the promoter occupied by RNAP. (D) The binding positions of YeiE, YieP, YiaJ, and YafC from the promoter are categorized according to the gene regulation. The abbreviations, D, U, and O indicate the downstream, upstream, and overlapped position, respectively. R and A indicate the regulation modes: repression and activation, respectively.
