Receptor for the bacteriocin pesticin and for the siderophore yersiniabactin. Induced in absence of iron. Weakly expressed by yersiniae located in the liver and the intestinal lumen. Strongly expressed in yersiniae located in the peritoneal cavity. Moderately expressed in yersiniae located in the spleen. This probably reflects the availability of iron for yersiniae. Belongs to the TonB-dependent receptor family.
