| Note(s): | We assigned a putative transcription start site to this promoter based on the observation that the majority of the σ54-dependent promoters, whose transcription start sites were determined experimentally, present a distance of 11 nucleotides between the transcription start site and the -12 box Barrios H,1999. Zaslaver et al. demonstrated in 2006, by means of a library of fluorescent transcription fusions, that this promoter can be transcribed in vitro Zaslaver A,2006. Based on this, a putative promoter was suggested, but the +1 site of the transcription initiation has not been determined, although there exists promoter activity. |
