The rotation of the β11-12 linker is a crucial control point for acid-sensing ion channel gating and motion of this linker is required for the channel to desensitize.
The dynamic structure of respiratory complex I from mesophilic bacterium is revealed and demonstrates existence of uncoupled conformations in the bacterial complex.

The manner in which protons control the conformational behaviour of mammalian peptide transporters is revealed through state-of-the-art molecular dynamics simulations supported by cell-based assays.
Structural analysis of the ATP synthase – in combination with evolutionary covariance analysis – reveals the fold of the a subunit and shows that the enzyme can adopt several different conformations, which support the Brownian ratchet model for generating rotation.

Allosteric reorganizations of a bacterial channel receptor are mapped along the protein structure, using the site-directed bimane quenching fluorescence technique, through parallel real-time conformational and electrophysiological recordings.
Computations based on detailed atomic models explain how the ATP-driven sodium-potassium pump avoids transporting the wrong type of ions in order to maintain the physiological concentration of sodium and potassium ions across the cell membrane.
