?
transcriptional regulator, ArgP family ArgP used to be known as IciA. ArgP is a positive regulator of argK. It is a negative autoregulator in presence of arginine. It competes with DnaA for oriC iteron (13-mer) binding. It activates dnaA and nrd transcription. It has been demonstrated to be part of the pho regulon (). ArgP mutants convey canavanine (an L-arginine structural homolog) sensitivity.
