Popis: Using cryo-EM, Chung et al. investigate conformational states of mammalian respiratory complex I to reveal an ubiquinone-10 molecule occupying the full length of the Q-binding channel. Molecular dynamics simulations suggest how the charge states of key residues influence the substrate binding pose.
