The pvsC gene of unknown function has been found in the iron-regulated vibrioferrin biosynthesis operon of Vibrio parahaemolyticus (Tanabe, T. et al., J. Bacteriol. 185: 6938-6949, 2003). The amino acid sequence deduced from the gene showed significant similarity to 12-transmembrane segment efflux pumps belonging to the major facilitator superfamily. A nonpolar deletion of pvsC in V. parahaemolyticus resulted in a reduced release of vibrioferrin into the medium. Vibrioferrin release could be regained by introducing the intact pvsC gene on a complementing plasmid. These results indicate that the pvsC gene product functions as an inner membrane exporter of vibrioferrin.
