Note(s): This promoter was identified by microarray assays with a mutant σ54 strain and a σ54-overexpressing strain, and by σ54-related promoter element identification Zhao K,2010
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.

Note(s): 1Yang et al. identified the binding site of PhoB Yang C,2012but did not identify the promoter regulated; therefore, there is a possibility that this binding site corresponds to another promoter, according to the function of PhoB. The binding site of this regulator, gCATGACAACATTGTGAAA, is located at bp -21 relative to the translation start site of yhjC Yang C,20121Yang et al. identified the binding site of PhoB Yang C,2012but did not identify the promoter regulated; therefore, there is a possibility that this binding site corresponds to another promoter, according to the function of PhoB.
