    A multifaceted analysis reveals two distinct phases of chloroplast biogenesis during de-etiolation in Arabidopsis

    Rosa Pipitone et al.
    Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.

    A pentameric protein ring with novel architecture is required for herpesviral packaging

    Allison L Didychuk et al.
    The first structures of Kaposi’s sarcoma-associated herpesvirus ORF68 and Epstein–Barr virus BFLF1, conserved and essential proteins required in herpesviruses, reveal new insights into viral genome packaging.

    Structure and mechanism of a phage-encoded SAM lyase revises catalytic function of enzyme family

    Xiaohu Guo et al.
    The first structure of a bacteriophage-encoded S-adenosyl methionine degrading enzyme was solved and demonstrated to catalyze a unimolecular lyase reaction occurring at the domain interface of a trimeric structure.

    TRIM37 prevents formation of centriolar protein assemblies by regulating Centrobin

    Fernando R Balestra et al.
    TRIM37 prevents the formation of centriolar protein assemblies through an atypical de novo assembly pathway that would otherwise threaten genome integrity.

    Structural basis for transcription complex disruption by the Mfd translocase

    Jin Young Kang et al.
    Seven distinct cryo-electron microscopy structures delineate the elaborate mechanism for how E. coli Mfd, a transcription repair coupling factor, disassembles the RNA polymerase transcription elongation complex to initiate transcription-coupled repair.

    High-resolution mapping of the neutralizing and binding specificities of polyclonal sera post-HIV Env trimer vaccination

    Adam S Dingens et al.
    HIV vaccine-induced binding and neutralizing antibody epitope specificities were mapped at high resolution directly from polyclonal sera, overcoming shortcomings in traditional serum mapping approaches and enabling highly detailed vaccine design.

    Properdin oligomers adopt rigid extended conformations supporting function

    Dennis V Pedersen et al.
    Combining electron microscopy and solution scattering demonstrated that properdin oligomers adopt extended rigid and well-defined conformations that are integral to the biological function of this complement regulator.
