A short review is given of recent work showing that the flagellar rotary motor of the bacterium Escherichia coli remodels to match its operating point (the fraction of time that it spins clockwise) to the requirements of the chemotaxis signaling network, and to provide the torque necessary to operate at different viscous loads.
本文简要回顾了近期的研究工作,这些研究表明,大肠杆菌的鞭毛旋转马达会进行重塑,以使其工作点(顺时针旋转的时间比例)与趋化信号网络的需求相匹配,并提供在不同粘性负载下运行所需的扭矩。
