Molecular motors are complex devices composed of many different parts that consume energy to perform various cellular activities. In short, molecular machines transform energy into useful work. Understanding the mechanistical aspects underlying these motors begins with generating a detailed description of their overall architecture and atomic organization. However, to uncover the core mechanisms energizing these motors it is essential to decode all of the molecular dynamics in atomic detail. Now, researchers reveal the architecture, complete functional cycle and the mechanism of such a molecular motor.
