Genes for ferrous iron transporters, feoABC and efeUOB, carried by the chromosome of Cronobacter spp. Arrows show the direction of transcription, and arrow fills identify genes encoding GTP-binding protein (probably permease) (diagonal lines), Fe-S-dependent transcriptional regulator of FeoABC expression (square), high-affinity iron permease (horizontal lines), transporter periplasmic protein (vertical lines), periplasmatic peroxidase protein (dots), and unknown function (white). The small filled boxes upstream of the operons show location of putative Fur boxes.
