Genomix SELEX patterns of group-S3 single-target TFs. Two TCA response regulators, KdpE (A) and TorR (B), were found to regulate only single targets, and thus are classified into group-S3 single-target TFs. In the absence of AcP for protein phosphorylation, KdpE bound to several sites (A1), of which the specific target within the spacer between the kdpABCDE and ybfA operons remained bound in the presence of ApC (A2). On the other hand, TorR bound only to the spacer between the torR and torcAD operons in the presence and absence of AcP (B1 and B2).
