Note(s): We assigned a putative transcriptional start site to this promoter based on the observation that the majority of the promoters, whose transcriptional start sites were determined experimentally, present a distance of 6 nucleotides between the transcriptional start site and the -10 box.

Note(s): 1By making use of microarray analyses, Constantinidou et al. Constantinidou C,2006 concluded that FNR activates yecR gene expression. They also identified a putative FNR-binding site upstream of the gene, but the sequence was not shown.3By making use of microarray analyses, Constantinidou et al.
