FIG. 1.

ς⁵⁴-dependent genes in E. coli. The known ς⁵⁴-dependent operons and their transcripts are shown in the context of neighboring genes. The open and solid boxes indicate counterclockwise and clockwise transcription, respectively. If the gene has been assigned a function, this is indicated by the gene name underneath. Boxes without gene names indicate that the gene has an unknown function. The sizes of the genes and their intergenic regions are to scale.
