摘要
微管马达在运输、有丝分裂和细胞运动等细胞功能中发挥着关键作用。它们以 ATP 水解为动力,将化学能转化为机械功,从而在微管上运动。虽然人们已经对它们沿微管长轴的运动进行了广泛研究,但有些马达还显示出轴外分量,这导致它们围绕微管进行螺旋运动,并在产生线性力的同时产生扭矩。对这些细微运动的了解扩展了我们对马达蛋白质动力学及其对细胞过程影响的理解。
Helical motion and torque generation by microtubule motors
Microtubule motors play key roles in cellular functions, such as transport, mitosis and cell motility. Fueled by ATP hydrolysis, they convert chemical energy into mechanical work, which enables their movement on microtubules. While their motion along the long axis of microtubules has been studied extensively, some motors display an off-axis component, which results in helical motion around microtubules and the generation of torque in addition to linear forces. Understanding these nuanced movements expands our comprehension of motor protein dynamics and their impact on cellular processes.
