| Note(s): | By making use of microarray analyses, it was concluded that FNR represses crr gene expression under anaerobiosis, although it is still not known which promoter is affected by FNR. Two putative FNR-binding sites were found: one of them is located upstream of the crr gene and the other one is located upstream of the ptsH gene, which is the first gene of the operon Salmon K,2003. Jeong et al. (2004) demonstrated experimentally that ArcA as well CRP regulate ptsH expression Jeong JY,2004 However, the authors did not mention the promoter that these regulators regulate (ptsH has five promoters). In addition, they did not mention the position or the effect exerted by these regulators. Under nitrogen-rich growth conditions, the expression of the ptsH gene increased in mutants for two genes that encode two terminal oxidases, cyoA and cydB, and in mutants for two transcriptional regulators, Fnr and Fur. However, under nitrogen-limited growth conditions, gene expression was decreased. It is unknown if the effects of the transcriptional regulators act directly on gene expression; also, it is unknown which of the five promoters that transcribe the gene could be regulated by the regulators Kumar R,2011 The expression of the gene ptsH is increased under acidic growth conditions in aerobiosis but not in microaerobiosis Marzan LW,2013 The increased expression of this gene is in agreement with the increased specific glucose consumption rate observed under acidic conditions Marzan LW,2013 |

1When the template is linear, transcriptional initiation is switched from POa to POb, 3 bp farther upstream from POa, and transcription becomes more CRP dependent. There is no PO expression in the absence of CRP or cAMP in the cell, unless glucose is present.1This binding site was determined from a computational prediction based on different statistical methods Oberto J.,2010 The function of the binding site was assigned according to the distance from the transcription start, with NagC as the transcriptional repressor.1When the template is linear, transcriptional initiation is switched from POa to POb, 3 bp farther upstream from POa, and transcription becomes more CRP dependent.
