The reversibly and repeatedly altered gliding motility of microtubules driven by kinesin on the photoresponsive monolayer surface is studied. It was confirmed that an azobenzene monolayer surface needs to have free amino terminal groups for the successful dynamic control of the motility of microtubule. The surface of the azobenzene monolayer with terminal amino groups can dynamically control the ATP hydrolysis activity of kinesin which resulted in the change in motility of the microtubules.
研究了驱动微管在光响应单分子层表面上可逆和重复改变的滑行运动能力。确认了苯偶氮单分子层表面需要有游离的氨基末端基团,以成功动态控制微管的运动能力。带有末端氨基基团的苯偶氮单分子层表面可以动态控制 kinesin 的 ATP 水解活性,从而导致微管运动能力的变化。
