    Competing scaffolding proteins determine capsid size during mobilization of Staphylococcus aureus pathogenicity islands

    Altaira D Dearborn et al.
    Cryo-electron microscopy and genetics show how Staphylococcus aureus pathogenicity island 1 hijacks the assembly pathway of a helper phage for its own propagation.

    Resurrection of a global, metagenomically defined gokushovirus

    Paul C Kirchberger, Howard Ochman
    Isolation of a gokushovirus capable of lysogenizing enterobacteria challenges previous notions about the biology of the most prolific phages within the Microviridae and facilitates experimental study in a model organism.

    Structural basis for AcrVA4 inhibition of specific CRISPR-Cas12a

    Gavin J Knott et al.
    An ancestral helical bundle governs whether the crRNA-processing nuclease of CRISPR-Cas12a is exploited by a phage-encoded allosteric anti-CRISPR.

    Engineered proteins detect spontaneous DNA breakage in human and bacterial cells

    Chandan Shee et al.
    Fluorescent derivatives of a bacteriophage protein that binds double-stranded ends can trap and label genome-destabilizing double-strand DNA breaks in bacterial and human cells, and illuminate the origins of spontaneous DNA breakage in both.

    MetaHiC phage-bacteria infection network reveals active cycling phages of the healthy human gut

    Martial Marbouty et al.
    Physical contacts of bacteria and phage genomes allow in situ exploration of underdocumented phage families in the gut.

    Biophysical properties of single rotavirus particles account for the functions of protein shells in a multilayered virus

    Manuel Jiménez-Zaragoza et al.
    In triple-layered rotavirus particles, strong interaction between the external and middle layers provides high mechanical strength for protection tasks, while weaker interaction between the middle and inner layers favors transcription.

    Discovery and characterization of a novel family of prokaryotic nanocompartments involved in sulfur metabolism

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

    Sampling the conformational space of the catalytic subunit of human γ-secretase

    Xiao-chen Bai et al.
    A masked cryo-EM image classification approach and the structure of an inhibitor-bound complex provide insights into the molecular flexibility of the catalytic subunit of gamma-secretase.

    Mechanism for nuclease regulation in RecBCD

    Martin Wilkinson et al.
    DNA unwinding triggers a conformational change in the RecD subunit of E. coli RecBCD helicase-nuclease that is transferred through the RecC subunit to activate the nuclease domain of the RecB subunit.
