Schematic representation of the uvrA-ssb divergent pair and the ruvCAB operon in different Vibrionaceae species. The figure illustrates the persistence of ssb regulation despite gene insertions and the disruption of the ruvCAB operon by gene insertions in some Vibrio species. Genes are represented by filled arrows. Grey-filled arrows correspond to genes that do not constitute part of the canonical uvrA-ssb and ruvCAB elements. Black triangles indicate predicted LexA-binding sites. GenBank accession numbers and absolute genome coordinates for each bacterial species are provided for reference.
