    Structures of diverse poxin cGAMP nucleases reveal a widespread role for cGAS-STING evasion in host–pathogen conflict

    James B Eaglesham et al.
    Poxin enzymes are a diverse family of insect and viral 2′3′-cGAMP nucleases, which evolved from self-cleaving RNA virus accessory proteases.

    Interplay between bacterial deubiquitinase and ubiquitin E3 ligase regulates ubiquitin dynamics on Legionella phagosomes

    Shuxin Liu et al.
    A novel bacterial deubiquitinase with multiple chain types specificity regulates the association of ubiquitinated proteins on the phagosome of Legionella pneumophila.

    The Sec1/Munc18 protein Vps45 holds the Qa-SNARE Tlg2 in an open conformation

    Travis J Eisemann et al.
    Whereas in a paradigmatic structure an SM protein chaperone clamps its client SNARE shut, a second structure demonstrates that an SM protein can also hold its SNARE open to promote assembly.

    Membrane insertion of α-xenorhabdolysin in near-atomic detail

    Evelyn Schubert et al.
    Cryo-EM and X-ray structures of α-xenorhabdolysin in soluble and pore form of Xenorhabdus nematophila give novel insights into the mechanism of action of bi-component α-pore-forming toxins.

    Architecture and RNA binding of the human negative elongation factor

    Seychelle M Vos et al.
    The structural architecture of the 4-subunit, RNA-binding human negative elongation factor NELF is derived by a combination of X-ray crystallography and protein crosslinking.

    9Å structure of the COPI coat reveals that the Arf1 GTPase occupies two contrasting molecular environments

    Svetlana O Dodonova et al.
    A molecular model of the assembled COPI coat, determined by cryo-electron tomography of an in vitro reconstituted budding reaction, reveals details of interactions mediating coat assembly and shows the binding site of ArfGAP2.

    A composite double-/single-stranded RNA-binding region in protein Prp3 supports tri-snRNP stability and splicing

    Sunbin Liu et al.
    Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.

    Scaffold nucleoporins Nup188 and Nup192 share structural and functional properties with nuclear transport receptors

    Kasper R Andersen et al.
    Components of the nuclear pore complex share structural and functional features with soluble nuclear transport receptors, which suggests that there may be an evolutionary relationship between these two types of protein.

    Super Spy variants implicate flexibility in chaperone action

    Shu Quan et al.
    Lab-evolved 'super Spy' chaperones show enhanced flexibility, which allows them to bind to and stabilize proteins more effectively than natural chaperones.

    An interbacterial DNA deaminase toxin directly mutagenizes surviving target populations

    Marcos H de Moraes et al.
    Interbacterial interactions can promote mutagenesis, and possibly adaptation, when intoxicated cells survive exposure to type VI secretion-delivered DNA deaminase toxins.
