The mechanisms underlying cohesin ATPase activity are poorly understood. Here, we characterize distinct steps of the human cohesin ATPase cycle and show that the SMC1A and SMC3 ATPase domains undergo specific but concerted structural rearrangements along this cycle. Specifically, whereas the proximal coiled coil of the SMC1A ATPase domain remains conformationally stable, that of the SMC3 displays an intrinsic flexibility. The ATP-dependent formation of the heterodimeric SMC1A/SMC3 ATPase module (engaged state) favors this flexibility, which is counteracted by NIPBL and DNA binding (clamped state). Opening of the SMC3/RAD21 interface (open-engaged state) stiffens the SMC3 proximal coiled coil, thus constricting together with that of SMC1A the ATPase module DNA-binding chamber. The plasticity of the ATP-dependent interface between the SMC1A and SMC3 ATPase domains enables these structural rearrangements while keeping the ATP gate shut.
