Involvement of the Vibrio parahaemolyticus pvsC gene in export of the siderophore vibrioferrin.

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