    Breakage of the oligomeric CaMKII hub by the regulatory segment of the kinase

    Deepti Karandur, Moitrayee Bhattacharyya ... John Kuriyan
    Activation and autophosphorylation of CaMKII releases the regulatory segment, which can then bind to and destabilize the hub assembly by trapping large fluctuations in the hub architecture.

    Structural variability and concerted motions of the T cell receptor – CD3 complex

    Prithvi R Pandey, Bartosz Różycki ... Thomas R Weikl
    The orientation of the TCR extracellular domain is highly variable and coupled to characteristic structural changes throughout the TCR - CD3 complex.

    Changes in the free-energy landscape of p38α MAP kinase through its canonical activation and binding events as studied by enhanced molecular dynamics simulations

    Antonija Kuzmanic, Ludovico Sutto ... Modesto Orozco
    Extensive molecular dynamics simulations enhanced by advanced sampling techniques give a detailed view of p38α canonical activation mechanism, which reveals novel key electrostatic interactions that are put in context of existing experimental data.

    Evolution of cation binding in the active sites of P-loop nucleoside triphosphatases in relation to the basic catalytic mechanism

    Daria N Shalaeva, Dmitry A Cherepanov ... Armen Y Mulkidjanian
    In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.

    Disulfide bridge-dependent dimerization triggers FGF2 membrane translocation into the extracellular space

    Fabio Lolicato, Julia P Steringer ... Walter Nickel
    Disulfide-bridged fibroblast growth factor 2 (FGF2) dimerization at the inner plasma membrane leaflet produces the building block for higher FGF2 oligomers that drive FGF2 membrane translocation into the extracellular space.

    Structure of the connexin-43 gap junction channel in a putative closed state

    Chao Qi, Silvia Acosta Gutierrez ... Volodymyr M Korkhov
    Cryo-EM structures and molecular dynamics simulations of Cx43 gap junction channel and hemichannel reveal a putative closed state.

    Structure-guided glyco-engineering of ACE2 for improved potency as soluble SARS-CoV-2 decoy receptor

    Tümay Capraz, Nikolaus F Kienzl ... Johannes Stadlmann
    Molecular dynamics simulation assisted engineering of recombinant soluble human ACE2 N-glycosylation by site-directed mutagenesis or glycosidase treatment yields a superior SARS-CoV-2 decoy receptor.

    The selectivity of the Na+/K+-pump is controlled by binding site protonation and self-correcting occlusion

    Huan Rui, Pablo Artigas, Benoît Roux
    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.

    Subtype-specific responses of hKv7.4 and hKv7.5 channels to polyunsaturated fatty acids reveal an unconventional modulatory site and mechanism

    Damon JA Frampton, Koushik Choudhury ... Sara I Liin
    Polyunsaturated fatty acids facilitate or impede Kv7 channel activation, depending on channel subtype and their dominant functional site(s).

    Identification of electroporation sites in the complex lipid organization of the plasma membrane

    Lea Rems, Xinru Tang ... Lucie Delemotte
    Advanced data analysis of molecular dynamics simulations of complex lipid membranes provides a quantitative and predictive model of the molecular features that control electroporation.
