Deletion of the mviN virulence gene in Salmonella enterica serovar. Typhimurium greatly reduces virulence in a mouse model of typhoid-like disease. Open reading frames encoding homologs of MviN have since been identified in a variety of bacteria, including pathogens and non-pathogens and plant-symbionts. In the nitrogen-fixing symbiont Rhizobium tropici, mviN is required for motility. The MviM protein is predicted to be membrane-associated.
