Protein
Sodium-type polar flagellar protein MotX
Organism
Vibrio parahaemolyticus serotype O3:K6 (strain RIMD 2210633)
Function
The power to drive the polar flagellar rotary motor of V.parahaemolyticus is derived from the transmembrane potential of sodium ions. Force is generated by the motor on coupling of the movement of ions across the membrane to rotation of the flagellum. MotX interacts with MotY, which is the presumed stationary component of the motor. MotX may form a sodium channel.
