生物马达是否以有规律的步伐运动?为了解决这个问题,我们构建了具有空间和时间灵敏度的仪器,以解决分子尺度上的运动。我们沉积的硅珠携带单分子的马达蛋白驱动蛋白的微管使用光镊和分析其运动下的控制负载的干涉。我们发现,驱动蛋白的运动与8纳米的步骤。
Do biological motors move with regular steps? To address this question, we constructed instrumentation with the spatial and temporal sensitivity to resolve movement on a molecular scale. We deposited silica beads carrying single molecules of the motor protein kinesin on microtubules using optical tweezers and analysed their motion under controlled loads by interferometry. We find that kinesin moves with 8-nm steps.
