    Functional cross-talk between allosteric effects of activating and inhibiting ligands underlies PKM2 regulation

    Jamie A Macpherson et al.
    Specific residues within an enzyme integrate allosteric inputs that originate from distinct ligand-binding pockets.

    Quiescence unveils a novel mutational force in fission yeast

    Serge Gangloff et al.
    The quiescence-driven mutational landscape reveals replication-independent mutagenesis as a novel evolutionary force.

    The elemental mechanism of transcriptional pausing

    Jason Saba et al.
    Biochemical analyses of transcription complexes, including kinetic studies and probes of translocational and conformational states, establish the elemental mechanism of pausing, which underlies regulation of gene expression in all organisms.

    Random-sequence genetic oligomer pools display an innate potential for ligation and recombination

    Hannes Mutschler et al.
    Random sequence RNA pools display an innate capacity for ligation and recombination, enabling them to “bootstrap” themselves towards higher compositional, informational and structural complexity.

    Ataxin-1 oligomers induce local spread of pathology and decreasing them by passive immunization slows Spinocerebellar ataxia type 1 phenotypes

    Cristian A Lasagna-Reeves et al.
    Building on previous work (Lasagna-Reeves et al., 2015) it is shown that polyglutamine ATXN1 oligomers propagate locally in SCA1 mice, and that passive immunotherapy targeting soluble oligomers can lead to an improvement in motor coordination and a modest increase in life span.

    ParB spreading on DNA requires cytidine triphosphate in vitro

    Adam SB Jalal et al.
    A biochemical reconstitution shows that the accumulation of Caulobacter crescentus ParB on DNA requires cytidine triphosphate and a closed DNA substrate in vitro.

    Subcellular drug targeting illuminates local kinase action

    Paula J Bucko et al.
    Genetically-encoded platforms direct kinase inhibitor drugs to organelles to reveal new dimensions of local kinase signaling.

    CDK9-dependent RNA polymerase II pausing controls transcription initiation

    Saskia Gressel et al.
    CDK9 inhibition in human cells uncovers that Pol II pause duration regulates the frequency of productive transcription initiation.

    Biophysical clocks face a trade-off between internal and external noise resistance

    Weerapat Pittayakanchit et al.
    Molecular clocks that are robust to external fluctuations are vulnerable to internal fluctuations and vice versa.

    Two distinct DNA sequences recognized by transcription factors represent enthalpy and entropy optima

    Ekaterina Morgunova et al.
    The epistasis observed in TF-DNA binding preferences can be explained by the presence of two optima of very similar Gibbs energy that are located relatively far from each other in sequence space.
