    Large-scale whole genome sequencing of M. tuberculosis provides insights into transmission in a high prevalence area

    JA Guerra-Assunção et al.
    A study of tuberculosis cases in the Karonga district of Malawi reveals that the main lineages of M. tuberculosis differ in their transmission patterns and virulence.

    Compensatory evolution drives multidrug-resistant tuberculosis in Central Asia

    Matthias Merker et al.
    The genetic make-up of dominating MDR-TB clades in Central Asia is shaped by programmatic and socio-economic changes that led to fixation of resistance and bacterial fitness related mutations in the Soviet era.

    Structure and function of the mycobacterial transcription initiation complex with the essential regulator RbpA

    Elizabeth A Hubin et al.
    The essential mycobacterial transcription factor RbpA interacts with promoter DNA and cooperates with another essential transcription factor, CarD, to stimulate the formation of an intermediate leading to the open promoter complex.

    A unifying mechanism for the biogenesis of membrane proteins co-operatively integrated by the Sec and Tat pathways

    Fiona J Tooke et al.
    Bioinformatics and experimental approaches identify families of membrane proteins requiring the co-ordinated action of the Sec pathway and Tat pathways for their integration and define features of the polypeptides that mediate interaction with these pathways.

    Ribosomal mutations promote the evolution of antibiotic resistance in a multidrug environment

    James E Gomez et al.
    Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.
