    Structural basis of interprotein electron transfer in bacterial sulfite oxidation

    Aaron P McGrath et al.
    A structural and functional analysis of the electron transfer complex between a sulfite oxidase and its redox protein partner reveals an elegant compromise between the requirements for fast and efficient electron transfer and reaction specificity.

    Extensive horizontal gene transfer in cheese-associated bacteria

    Kevin S Bonham et al.
    The identification of horizontally transferred genes, and commonly transferred functions, can provide a window into the selective forces acting on species within an ecosystem.

    Overall energy conversion efficiency of a photosynthetic vesicle

    Melih Sener et al.
    The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.

    Evolutionary transitions between beneficial and phytopathogenic Rhodococcus challenge disease management

    Elizabeth A Savory et al.
    The horizontal acquisition of virulence plasmids is potentiated by production practices in plant nurseries and is sufficient to transition Rhodococcus from being beneficial to being pathogenic.

    Francisella tularensis enters a double membraned compartment following cell-cell transfer

    Shaun P Steele et al.
    Francisella tularensis spreads from cell to cell when macrophages engulf small portions of infected cells upon cell contact, forming distinctive a double membraned endosome containing multiple bacteria per individual vacuole.

    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.

    Trogocytosis-associated cell to cell spread of intracellular bacterial pathogens

    Shaun Steele et al.
    Live intracellular bacterial pathogens can transfer from infected cells to uninfected macrophages upon cell-to-cell contact.

    The DNA-binding protein HTa from Thermoplasma acidophilum is an archaeal histone analog

    Antoine Hocher et al.
    In Thermoplasma acidophilum, an archaeon without histones, a DNA-binding protein acquired from bacteria via horizontal gene transfer mediates histone-like chromatin architecture.

    Toxoplasma gondii F-actin forms an extensive filamentous network required for material exchange and parasite maturation

    Javier Periz et al.
    In contrast to current knowledge that predicts that apicomplexan actin is unconventional, use of Chromobodies demonstrate that Toxoplasma F-actin forms a long, stable, highly dynamic tubular network that is required for material transfer and parasite maturation.
