A combination of equilibrium and nonequilibrium molecular dynamics simulations is an effective tool to study allosteric communications in ultrafast enzymes that show little or no conformational changes.

A protein-bounded organelle-like compartment from Synechococcus elongatus PCC 7942 is upregulated under sulfur starvation and contains a cysteine desulfurase cargo enzyme.

Cryo-EM and chemical cross-linking studies yield an atomic resolution structure of a conserved remodeling machinery in messenger ribonucleoprotein maturation/nuclear export and insights into its coordinated function with a serine–arginine protein.

Mutating a highly conserved intramembrane salt bridge unmasks structural and functional coupling between channel gating and ion permeation in the muscle nicotinic receptor.

The dual functional protein, Gorab, associates with the Golgi as a dimer but as a monomer with the procentriole cartwheel protein, Sas6, to mediate centriole duplication.

NHE1-CaM complexes of multiple stoichiometries regulate cellular Ca²⁺-dependent NHE1 activity and can contribute to NHE1 dimerization, the latter shown by the NMR structure of CaM linking two NHE1 cytosolic tails.

Analysis of conformational changes indicates that activation of acid-sensing ion channels involves protonation of diverse extracellular sites and interaction of interdomain loops with the upper ends of transmembrane helices.

A summary of the current “state-of-the-field” of single-molecule FRET used for probing biomolecular structural dynamics.

Structures of the GluK2/K5 kainate receptor reveal the heteromer architecture and how the receptor organizes in apo, antagonist-bound, and desensitized states.

A single-stranded DNA binding protein stimulates helicase-mediated DNA unwinding by transiently activating a latent processivity switch in the helicase.
