Illustration of newly discovered mechanism allowing kinesin to “walk” down a microtubule. A green kinesin molecule with an attached yellow fluorophore is shown passing through a blue laser as it rotates step by step along a red and purple microtubule, fueled by blue ATP molecules that are hydrolyzed into orange ADP and phosphate groups.
