Genomic organization of genes predicted to be regulated by two transcription factors from the CRP/FNR-family. Black circles denote operators for the CO-responsive regulator CooA. Blue circles and squares denote predicted sites of the hypothetical transcriptional factor HcpR with two different consensus sequences, respectively. w, HcpR site with a weak score; ..., a set of gene names that are not shown. See Figure 1 legend for abbreviations.
