Note(s): 1It seems that DnaA bound first at a site between the transcription start site and the -10 sequence on the upper strand triggered the cooperative binding upon an increase of the number of bound molecules.8It seems that DnaA bound first at a site between the transcription start site and the -10 sequence on the upper strand triggered the cooperative binding upon an increase of the number of bound molecules.
