    Synergy between RecBCD subunits is essential for efficient DNA unwinding

    Rani Zananiri et al.
    A new optical tweezers assay sheds light on the mechanism of cooperation and force generation by the subunits of RecBCD, critical for the repair of double strand breaks in bacteria.

    Conformational and dynamic plasticity in substrate-binding proteins underlies selective transport in ABC importers

    Marijn de Boer et al.
    Selective import via bacterial ABC importers is facilitated by a hitherto unrecognized complexity in the conformational dynamics of the substrate-binding proteins.

    Tuning myosin-driven sorting on cellular actin networks

    Rizal F Hariadi et al.
    Competition between the antagonistic motor proteins myosin V and myosin VI finely tunes unidirectional transport of cargo on different actin architectures.

    Cooperative unfolding of distinctive mechanoreceptor domains transduces force into signals

    Lining Ju et al.
    New biophysical methods and analyses visualize in real-time a chain of coordinated single-molecular events on a living cell, enabling the inner workings of a mechanoreceptor important to biology to be elucidated.

    Small-molecule inhibitors identify the RAD52-ssDNA interaction as critical for recovery from replication stress and for survival of BRCA2 deficient cells

    Sarah R Hengel et al.
    Small molecule inhibitors identified in a biophysical high-throughout screening assay confirm the importance of the interaction between single-stranded DNA and the protein RAD52 for the survival of BRCA2-depleted cells.

    The mechanism of variability in transcription start site selection

    Libing Yu et al.
    Variability in bacterial transcription start site selection involves DNA “scrunching” and “anti-scrunching,” which may represent a general mechanism for start site selection in all organisms.

    Functional instability allows access to DNA in longer transcription Activator-Like effector (TALE) arrays

    Kathryn Geiger-Schuller et al.
    Single molecule DNA-binding trajectories and deterministic modeling analyses demonstrate a functional role for high energy partly folded states in Transcription Activator-Like Effectors that could improve future TALEN design.

    The innate immune sensor IFI16 recognizes foreign DNA in the nucleus by scanning along the duplex

    Sarah A Stratmann et al.
    The scanning-assisted clustering mechanism of IFI16 not only allows efficient assembly on exposed foreign-dsDNA, but also suppresses the engagement of chromatinized self-dsDNA.

    Observation of long-range tertiary interactions during ligand binding by the TPP riboswitch aptamer

    Van K Duesterberg et al.
    The combined use of optical trapping and single-molecule FRET permits the study of riboswitch structure formation and conformational dynamics at the same time.
