Arrangement of genes around flgZ homologs in select, diverse bacteria. (A) The flgZ gene (red) in H. pylori 26695 is flanked by hp0959 (black) and kdtA (yellow). In W. succinogenes DSM 1740 the flgZ and hp0959 homologs (locus number WS2117) are fused. Arrows depicting genes are not drawn to scale. (B) The arrangements of genes surrounding flgZ homologs of bacteria from diverse taxonomic groups are indicated. Bacteria and the phylum or subphylum to which they belong (in parentheses) are: Porphyromonas gingivalis ATCC 33277 (Bacteroidetes); Clostridium carboxidivorans P7 (Firmicutes); Desulfatibacillum alkenivorans AK-01 (Deltaproteobacteria); Denitrovibrio acetiphilus N2460, DSM 12809 (Deferribacteres); Thermodesulfovibrio yellowstonii DSM 11347 (Nitrospirae); Borrelia burgdorferi B31 (Spirochaetes); and Planctomyces maris DSM 8797 (Planctomycetes). Genes whose products share similar functions are color coded as follows: DNA primase (dnaG) (green); σ70 family protein (blue); tRNA-Met (orange); and RNase H (rnhA) (dark purple). Unique genes are indicated by white arrows, except for the gene encoding the catalytic RNA of RNase P (light purple) which is located downstream of the flgZ homolog in B. burgdorferi B31. Locus numbers for the genes (left to right) are as follows: PGN_1989 and PGN_1990 (P. gingivalis); CcarbDRAFT_2245 through CcarbDRAFT_2240 (C. carboxidivorans); Dalk_3077 through Dalk_3074 (D. alkenivorans); DacetDRAFT_16020 through DacetDRAFT_16060 (D. acetiphilus); THEYE_A1028 through THEYE_A1032 (T. yellowstonii); BB0710 through BB0713 plus BB_R0040 (B. burgdorferi); PM8707T_20723 through PM8707T_20733 (P. maris).
