    Dna2 nuclease-helicase structure, mechanism and regulation by Rpa

    Chun Zhou et al.
    X-ray crystallography reveals that the Dna2 nuclease-helicase contains a long tunnel through which single-stranded DNA threads, and an allosteric mechanism for displacing the DNA-binding protein Rpa that restricts cleavage to the proper polarity.

    Fidaxomicin jams Mycobacterium tuberculosis RNA polymerase motions needed for initiation via RbpA contacts

    Hande Boyaci et al.
    Cryo-electron microscopy structures show how the clinically used antimicrobial fidaxomicin binds and inhibits Mycobacterium tuberculosis RNA polymerase by acting like a doorstop to jam the enzyme in an open conformation via the general transcription factor RbpA.

    Temporal network analysis identifies early physiological and transcriptomic indicators of mild drought in Brassica rapa

    Kathleen Greenham et al.
    Coupled physiology and gene expression, measured over a two-day time course, reveals specific time-of-day responses to the early stages of drought in Brassica rapa.

    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.

    Protein translocation channel of mitochondrial inner membrane and matrix-exposed import motor communicate via two-domain coupling protein

    Rupa Banerjee et al.
    Two domains of the peripheral membrane protein Tim44 interact with two different sectors of a translocase to coordinate the translocation of proteins across the inner mitochondrial membrane.

    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.

    Tumor Angiogenesis: Taking aim at Sox18

    Injune Kim, Gou Young Koh
    A small molecule called Sm4 can disrupt interactions involving a transcription factor called Sox18, while having little impact on other members of the SoxF family.
