LptC regulates the LPS entry gate in LptB2FG, likely through a dynamic behavior of its transmembrane helix, while the β-jellyroll domains are tethered in the periplasm.
The mechanism of substrate binding cooperativity in human thymidylate synthase does not derive from millisecond dynamic interconversion between active and inactive conformations in solution, but instead results primarily from differential changes in faster side-chain motions (conformational entropy), facilitated by a disordered N-terminus.
Chaperones from different families and classes synergistically target different stages of tau aggregation, thus preventing pathological amyloid formation.

Pulse electron paramagnetic resonance on intact Escherichia coli reveals a substrate-induced structural transition in BtuB, the vitamin B12 transporter, which is not seen in reconstituted membranes and indicates a mechanism of transport.

A spectroscopic analysis of the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA)-phospholamban membrane complex reveals the importance of the relative transmembrane orientation for inhibition or activation of the ATPase.

The strongest peak frequency of brain oscillations in a brain area decreases significantly, gradually and robustly along the posterior-anterior axis following the global hierarchy from early sensory to higher order areas.

The cysteine pair oxidation state in nDsbD acts as a ‘switch’ controlling the presence or absence of frustration in the active-site and determining the dynamic behavior of the cap loop.
