Note(s): 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.
There are two transcription start sites (TSSs) for the yafN promoter. Here we associated the TTS more upstream to this promoter. In addition, Christensen-Dalsgaard et al. (2009) showed -10 and -35 boxes which are far from the normal position 19763168 However, the -10 box associated with the yafN promoter also shows an unusual distance Christensen-Dalsgaard M,2010
