    Structure of a type IV pilus machinery in the open and closed state

    Vicki AM Gold et al.
    Electron cryo-tomography reveals a huge conformational change in the secretin domain of the type IV pilus machinery that occurs when the channel opens for pilus extrusion.

    Kin cell lysis is a danger signal that activates antibacterial pathways of Pseudomonas aeruginosa

    Michele LeRoux et al.
    The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

    Structural basis of ribosomal peptide macrocyclization in plants

    Joel Haywood et al.
    The first crystal structure of an active plant asparaginyl endopeptidase reveals a tetrahedral intermediate state in its active site, which may help to explain why these enzymes have been independently recruited to perform peptide macrocyclization.

    Antibacterial gene transfer across the tree of life

    Jason A Metcalf et al.
    Parallel horizontal gene transfer has spread a bacteriolytic gene family to all domains of life, and has bestowed a niche-transcending adaptation in recipients that must deploy antibacterial molecules to survive in a bacterial world.

    Bacterial symbiont subpopulations have different roles in a deep-sea symbiosis

    Tjorven Hinzke et al.
    Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.

    Inter-membrane association of the Sec and BAM translocons for bacterial outer-membrane biogenesis

    Sara Alvira et al.
    The protein translocation apparatus of the inner- (Sec) and outer-membrane (BAM) interact to form a trans-periplasmic super-complex capable of long-range, PMF-dependent conformational changes to facilitate efficient outer-membrane protein maturation.

    Phosphatidylcholines from Pieris brassicae eggs activate an immune response in Arabidopsis

    Elia Stahl et al.
    Plants detect the presence of phospholipids in eggs from a herbivorous insect and trigger innate immunity.

    A conserved cell division protein directly regulates FtsZ dynamics in filamentous and unicellular actinobacteria

    Félix Ramos-León et al.
    Identification of a novel regulator that directly influences the assembly and function of the cell division machinery in industrially and medically important bacteria.

    Structure of bacterial phospholipid transporter MlaFEDB with substrate bound

    Nicolas Coudray et al.
    Structure of MlaFEDB ABC transporter with substrate bound in the outward-open pocket of MlaE provides mechanistic insights into lipid transport within the Gram-negative bacterial cell envelope.

    An ECF-type transporter scavenges heme to overcome iron-limitation in Staphylococcus lugdunensis

    Angelika Jochim et al.
    An ECF-type transporter serves as broad-spectrum heme iron scavenger and allows an opportunistic pathogen to use multiple eukaryotic hemoproteins to overcome nutritional iron-limitation.
