Analyses of the Roles of the Three cheA Homologs in Chemotaxis of Vibrio cholerae

Abstract excerpt

The Vibrio cholerae genome revealed the presence of multiple sets of chemotaxis genes, including three cheA gene homologs. We found that the cheA-2, but not cheA-1 or cheA-3, gene is essential for chemotaxis under standard conditions. Loss of chemotaxis had no effect on virulence factor expression in vitro.
