The proteins, PomA, PomB, MotX and MotY have been identified as the motor proteins that are necessary for the flagella rotation. The T ring newly found by us is necessary for the assembly. The structure of the component protein, MotY, of the T ring is determined with a 2.9 Å resolution. We proposed the molecule dynamic model of the flagella motor proteins to assemble as a functional motor. We showed that the C ring structure was easily dissociated from the flagella base body. Furthermore we found that FlgT was the basal body component to construct a ring outside of the LP ring. The ring was named an H ring. The new ring may contribute on the Vibro motor function as a strong shaft to support the high-speed rotation of the motor.
