    The Acinetobacter baumannii Mla system and glycerophospholipid transport to the outer membrane

    Cassandra Kamischke et al.
    An Acinetobacter baumannii ABC transporter likely facilitates transport of glycerophospholipids from the inner to the outer membrane.

    Preacinetobactin not acinetobactin is essential for iron uptake by the BauA transporter of the pathogen Acinetobacter baumannii

    Lucile Moynié et al.
    The pathogen Acinetobacter baumannii recognises preacinetobactin not acinetobactin, yet appears likely to translocate both compounds through a mixed complex.

    Bacterial Evolution: The road to resistance

    Devon M Fitzgerald
    The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.

    Evolutionary pathways to antibiotic resistance are dependent upon environmental structure and bacterial lifestyle

    Alfonso Santos-Lopez et al.
    Bacteria growing in biofilms evolve antimicrobial resistance via different pathways and generate greater genetic diversity than well-mixed populations, selecting fitter but less resistant genotypes.

    Insights into the key determinants of membrane protein topology enable the identification of new monotopic folds

    Sonya Entova et al.
    Key sequence motifs, defined using the first reported structure of a monotopic membrane protein with a reentrant helix, enable identification of new monotopic membrane protein families previously predicted as membrane spanning.

    Inter-species population dynamics enhance microbial horizontal gene transfer and spread of antibiotic resistance

    Robert M Cooper et al.
    Killing their neighbors allows bacteria to steal genes, including antibiotic resistance genes, which we observed under a microscope, quantified, modeled, and predicted potentially guiding strategies to combat it.

    An NAD+-dependent novel transcription factor controls stage conversion in Entamoeba

    Dipak Manna et al.
    Cellular NAD+ levels change during stage conversion and regulate function of a novel transcription factor that controls developmental switching in the human pathogen Entamoeba histolytica.

    Massive antibody discovery used to probe structure–function relationships of the essential outer membrane protein LptD

    Kelly M Storek et al.
    Dispensable loops shield the functionally-important extracellular loops of the essential Gram-negative bacterial outer membrane protein LptD from antibody interference.
