Gene(s): ptsH, ptsI, crr   Genome Browser M3D Gene expression COLOMBOS
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 |CITS: [12754220]|.
Jeong et al. (2004) demonstrated experimentally that ArcA as well CRP regulate ptsH expression |CITS:[15252051]|. 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 |CITS:[21272324]|.
The expression of the gene ptsH is increased under acidic growth conditions in aerobiosis but not in microaerobiosis |CITS:[23274360]|. The increased expression of this gene is in agreement with the increased specific glucose consumption rate observed under acidic conditions |CITS:[23274360]|.
