Gene regions associated with iron acquisition in C. variabile DSM 44702. Gene clusters probably involved in the uptake of ferric iron (fiu) and iron-siderophores (siu) are presented. Detected DtxR binding sites are indicated as black boxes upstream of the coding regions. Genes encoding iron uptake and utilization systems are colored according to their functional assignments, whereas grey arrows indicate genes of unknown functions present in the siu clusters.
