    Nucleosome conformation dictates the histone code

    Matthew R Marunde, Harrison A Fuchs ... Catherine A Musselman
    NMR spectroscopy, dCypher assays, and CUT&RUN demonstrate that occlusion of the histone tails in the nucleosome context alters histone PTM specificity for a tandem of reader domains.

    Asymmetric framework motion of TCRαβ controls load-dependent peptide discrimination

    Ana C Chang-Gonzalez, Robert J Mallis ... Wonmuk Hwang
    All-atom molecular dynamics simulations of an αβ T-cell receptor complexed with the major histocompatibility complex molecule presenting wild-type or mutant antigenic peptides reveal how it uses conserved framework motion to discriminate antigens by leveraging physiological force applied during immune surveillance.

    Structural and biophysical analysis of a Haemophilus influenzae tripartite ATP-independent periplasmic (TRAP) transporter

    Michael J Currie, James S Davies ... Rachel A North
    Structure of the dimeric Haemophilus influenzae TRAP transporter (SiaQM) reveals two Na+ sites, the substrate-binding site and lipid-binding sites, and weak but promiscuous binding of SiaP to SiaQM.

    Pharmacologic hyperstabilisation of the HIV-1 capsid lattice induces capsid failure

    KM Rifat Faysal, James C Walsh ... Till Böcking
    The anti-HIV drug lenacapavir breaks the HIV capsid by stabilising regions of low curvature at the expense of maintaining a closed shell, leading to loss of viral DNA synthesis and inhibition of infection.

    Discovery of lipid binding sites in a ligand-gated ion channel by integrating simulations and cryo-EM

    Cathrine Bergh, Urška Rovšnik ... Erik Lindahl
    A combination of molecular dynamics simulations and electron cryomicroscopy characterizes interactions of a pentameric ligand-gated ion channel with 25 lipid molecules, specifically in a functional state in which they were not previously observed.
