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.

Transcription unit          
Name: acs-yjcHG
Gene(s): actP, yjcH, acs   Genome Browser M3D Gene expression COLOMBOS
Note(s): Transcription of acs may be negatively regulated by IclR through an indirect effect Kumari S,2000Shin S, Song SG, Lee DS, Pan JG, Park C,1997. Fnr activates the transcription of acs by binding to two sites located close to the transcription start site. This has been demonstrated by gene expression analysis and protein binding to the region, but the specific sequences of the sites were not reported Kumari S,2000.
Based on arcA deletion experiments, it appears that ArcA-P represses the acs-yjcH-actP operon, resulting in a lower rate of acetate uptake and assimilation Veeravalli K, Schindler T, Dong E, Yamada M, Hamilton R, Laird MW,2018
The expression of the gene acs is diminished under oxygen limitation Kawaguchi H, Miyagawa H, Nakamura-Tsuruta S, Takaya N, Ogino C, Kondo A,2019, and it is highly increased in the presence of pyruvate El-Mansi M, Phue JN, Shiloach J,2021.
