    Matrix-trapped viruses can prevent invasion of bacterial biofilms by colonizing cells

    Matthew C Bond et al.
    Microfluidic culture and high-resolution 3-D microscopy establish that bacteriophages trapped in the outer matrix layers of a bacterial biofilm remain active and can prevent colonization of the biofilm by newly arriving bacteria.

    Dominant Vibrio cholerae phage exhibits lysis inhibition sensitive to disruption by a defensive phage satellite

    Stephanie G Hays, Kimberley D Seed
    Genetic and molecular analyses identify and characterize an evolutionary battle over lysis timing wherein a bacteriophage delays lysis through lysis inhibition while a defensive phage satellite accelerates lysis.

    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.

    Phage integration alters the respiratory strategy of its host

    Jeffrey N Carey et al.
    A temperate bacteriophage reprograms the oxygen response of a bacterial signaling system by replacing a host-encoded promoter with a phage-encoded promoter.

    A chimeric nuclease substitutes a phage CRISPR-Cas system to provide sequence-specific immunity against subviral parasites

    Zachary K Barth et al.
    Horizontal transfer of a sequence-specific DNA-binding domain allows a virus to destroy its subviral parasite and overcome parasite-mediated restriction.

    Mechanisms of opening and closing of the bacterial replicative helicase

    Jillian Chase et al.
    Analysis of the Escherichia coli DnaB helicase•bacteriophage λ helicase loader (λP) complex provides insights into helicase opening, delivery to the origin and ssDNA entry, and closing in preparation for translocation.

    Virus Engineering: ORACLE reveals a bright future to fight bacteria

    Willow Coyote-Maestas, James S Fraser
    A new way to alter the genome of bacteriophages helps produce large libraries of variants, allowing these bacteria-killing viruses to be designed to target species harmful to human health.

    Structure of a Holliday junction complex reveals mechanisms governing a highly regulated DNA transaction

    Gurunathan Laxmikanthan et al.
    The structure of a multi-protein DNA recombination reaction intermediate reveals how regulation is achieved by protein-mediated DNA wrapping around a core enzyme-substrate complex.

    Allosteric communication in DNA polymerase clamp loaders relies on a critical hydrogen-bonded junction

    Subu Subramanian et al.
    Deep mutagenesis of a clamp-loader complex reveals a critical hydrogen-bonded junction that is important for allosteric communication in oligomeric AAA+ ATPases.
