Genomic arrangements of rsb genes and homologues in other species. In R. capsulatus, the rbaV and rbaW genes are found together with the rbaY gene located elsewhere in the genome. In Rhodopseudomonas palustris, the VWY genes are organized in an apparent 3-gene operon. The rsbV and rsbW genes are found in an 8-gene operon with rsbRSTU, sigB and rsbX in Bacillus subtilis. B. cereus lacks rsb genes upstream of rsbV and a bacterioferritin (bfr) gene is found between sigB and rsbY, the PP2C serine phosphatase in this system.
