Note(s): In 1997 Lee et al. showed that ArgP binds to two regions in the intergenic region of the gene dnaA, acts as a dimer of dimers upstream of the transcription start site |CITS: [9254708]|, and binds as a dimer near the Shine-Dalgarno sequence of the gene dnaA |CITS: [8825783]|. Despite strong experimental evidence, those authors did not identify the center positions of the binding sites. According to this evidence, the curator has assigned three possible binding sites of 20 bp for ArgP, located at bp -69.5, -49.5, and 219.5 relative to the transcription start site of lysP. The curator identified the consensus sequence of ArgP and assigned the possible central position of these binding sites, based on similarity to consensus sequences.

Note(s): 2It has been shown that the dnaAN-recF operon is not regulated in vivo by ArgP Marbaniang CN,2011 However, ArgP slightly binds to the regulatory regions of dnaAp1 in vitro, as it exhibits low-affinity binding to ArgP Marbaniang CN,2011
