Abstract	In this work we demonstrate the existence in Vibrio anguillarum 775 (pJM1) of two chromosomal genes encoding outer membrane proteins that operate in the transport of ferric enterobactin. One of them is a novel receptor that we named FetA and the other is the already characterized FvtA that functions in the uptake of iron complexes of both enterobactin and vanchrobactin. Ferric enterobactin transport proficiency was resumed in double mutants for these two genes when they were complemented with either fetA or fvtA, whereas only the cloned fvtA could complement for ferric vanchrobactin transport. Quantitative RT-PCR assays demonstrated that transcription of the fetA gene is regulated by FetR, that is encoded upstream and in reverse orientation from fetA. This gene as well as fetA, are up-regulated in iron limiting condition in a Fur-dependent manner. The two divergent promoters are located in the intergenic region between fetR and fetA that has a putative Fur binding site and an IrgB binding site in the overlapping promoters of fetR and fetA. FetA and FetR show high homology to V. cholerae IrgA and IrgB respectively and the intergenic regions fetA–fetR and irgA–irgB are also highly related suggesting a vertical transmission of the fetA–fetR cluster from V. cholerae to V. anguillarum.
