Study on the structure and funciotion of supramolecular flagellar motor

其中，PomA、PomB、mox和MotY蛋白已被确定为鞭毛旋转所必需的运动蛋白。我们新发现的T环是装配所必需的。T环的组成蛋白MotY的结构以2.9 Å的分辨率确定。我们提出了鞭毛马达蛋白作为功能马达组装的分子动力学模型。结果表明，C环结构很容易与鞭毛基体分离。此外，我们发现FlgT是构建LP环外环的基础体成分。这个环被命名为H环。新的环可能有助于振动电机功能作为一个强大的轴，以支持电机的高速旋转。

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.
