    Structural characterization of NrnC identifies unifying features of dinucleotidases

    Justin D Lormand et al.
    Dinucleotidases, specialized enzymes that catalyze the final step in RNA degradation, have evolved independently and repeatedly to fulfill essential roles in cell growth.

    Ir56d-dependent fatty acid responses in Drosophila uncover taste discrimination between different classes of fatty acids

    Elizabeth B Brown et al.
    The taste system of fruit flies is activated by broad classes of fatty acids and can discriminate between different classes, revealing previously underappreciated complexity in the coding of tastants.

    Protomer alignment modulates specificity of RNA substrate recognition by Ire1

    Weihan Li et al.
    Biochemical analysis and computational modeling reveal how cells mechanistically control the quality of their proteomes and demonstrate that the precise alignment of subunits in oligomeric complexes can profoundly affect enzymatic properties.

    A novel DNA primase-helicase pair encoded by SCCmec elements

    Aleksandra Bebel et al.
    SCCmec genomic islands encode a novel primase-helicase pair in which priming ability is conferred upon an A-family DNA polymerase domain by a novel protein cofactor.

    CRISPR-Cas12a exploits R-loop asymmetry to form double-strand breaks

    Joshua C Cofsky et al.
    The DNA flanks on either side of an R-loop differ in stability, and CRISPR-Cas12 enzymes form double-strand breaks by targeting the more unstable flank with their single DNase active site.

    Mechanisms of nucleotide selection by telomerase

    Matthew A Schaich et al.
    The roles of key telomerase active site residues were elucidated to determine how telomerase selects the correct from the incorrect nucleotide to maintain telomere integrity.

    Aire-dependent genes undergo Clp1-mediated 3’UTR shortening associated with higher transcript stability in the thymus

    Clotilde Guyon et al.
    The Aire-dependent genes show a preference for short 3’UTR transcript isoforms resulting in the escape from the post-transcriptional repression mediated by miRNAs in medullary thymic epithelial cells.

    Cryo-EM structures demonstrate human IMPDH2 filament assembly tunes allosteric regulation

    Matthew C Johnson, Justin M Kollman
    Assembly of the human enzyme inosine monophosphate dehydrogenase 2 into filaments promotes substrate-dependent resistance to feedback inhibition by downstream products, promoting increased flux during proliferative states.
