FIG. 2.
Topology of riboflavin biosynthesis operons. Sequences were derived from fully sequenced genomes available from GenBank. Orientations of the genes involved in riboflavin biosynthesis or adjacent to those genes are given as arrows (not drawn to scale). Organisms (accession numbers) are as follows: Brucella meliloti 16 M chromosome I (NC 003317), Brucella suis 1330 chromosome I (NC 004310), Brucella abortus biovar 1 strain 9-941 chromosome I (NC 006932), Sinorhizobium meliloti 1021 (NC_003047), Mesorhizobium loti MAFF303099 (NC 002678), Bartonella henselae strain Houston-1 (NC 005956), Rhodopseudomonas palustris CGA009 (NC 005296), Bradyrhizobium japonicum USDA 110 (NC 004463), Caulobacter crescentus CB15 (NC_002696), Xanthomonas axonopodis pv. citri strain 306 (NC 003919), Xanthomonas oryzae KACC10331 (NC 006834), Xylella fastidiosa Temecula1 (NC_004556), Pseudomonas syringae pv. tomato strain DC3000 (NC_004578), Pseudomonas putida KT2440 (NC 002947), Methylococcus capsulatus strain Bath (NC 002977), Acinetobacter sp.
