Fuelled by ATP hydrolysis, dyneins generate force and movement on microtubules in a wealth of biological processes. A model for the mechanochemical cycle of dynein is emerging, in which nucleotide-driven flexing motions within the AAA+ ring of dynein alter the affinity of its microtubule-binding 'stalk' and reshape its mechanical element to generate movement.
