Conserved residues in diverse RsbR linkers. ClustalW alignment of the linker regions of RsbR paralogs from B. subtilis and L. monocytogenes plus the eight most diverse orthologs from Fig. S1 in the supplemental material, with the conserved positions shaded. Organism, paralog designation, and UniProt identifier indicate linker origin; lines and letters above alignment denote N-terminal and C-terminal domain boundaries and residue position within presumed heptad repeats; vertical numbers below the alignment are B. subtilis RsbRA residue numbers.
