Genetic context of yvrI in bacilli. (A) The gene order is shown as originally described for B. subtilis but also conserved in B. pumilis, B. licheniformis, and B. amyloliquefaciens. Positions of experimentally verified YvrI-dependent promoters in B. subtilis (angled arrows) are positionally conserved in all four species. Genetic contexts are also shown for L. sphaericus and Bacillus sp. strain 14905 (B), B. cereus AH1134 (C), and Bacillus sp. strain NRRLB-14911 (D). All other species listed in Table 1 either lack or have alternative genomic positions for yvrJ (black ORFs), oxdC, and yvrL. Genes upstream of the yvrI-yvrHa operon (grey ORFs) shown in panels B, C, and D (checkered ORFs) are not positionally conserved among these species. Gene position in panel B is for Bacillus sp. strain 14905.
