    Modular metabolite assembly in Caenorhabditis elegans depends on carboxylesterases and formation of lysosome-related organelles

    Henry H Le, Chester JJ Wrobel ... Frank C Schroeder
    Caenorhabditis elegans homologs of carboxylesterases that localize to intestinal organelles orchestrate the assembly of modular signaling molecules from building blocks that integrate diverse metabolic pathways.

    Molecular basis for substrate specificity of the Phactr1/PP1 phosphatase holoenzyme

    Roman O Fedoryshchak, Magdalena Přechová ... Richard Treisman
    Interaction of cofactor Phactr1 with PP1 creates a composite substrate-binding surface that defines the sequence specificity of the Phactr1/PP1 holoenzyme.

    Gradual compaction of the nascent peptide during cotranslational folding on the ribosome

    Marija Liutkute, Manisankar Maiti ... Marina V Rodnina
    HemK NTD cotranslational folding starts within the ribosome exit tunnel upon N-terminal helix synthesis and proceeds sequentially through a series of intermediates becoming less dynamic as the nascent chain grows.

    Feedback control of Wnt signaling based on ultrastable histidine cluster co-aggregation between Naked/NKD and Axin

    Melissa V Gammons, Miha Renko ... Mariann Bienz
    An unusual molecular mechanism has been revealed based on ultrastable histidine cluster co-aggregation underlying feedback control of an ancient cell communication pathway.

    A novel DNA primase-helicase pair encoded by SCCmec elements

    Aleksandra Bebel, Melissa A Walsh ... Phoebe A Rice
    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.

    Light-regulated allosteric switch enables temporal and subcellular control of enzyme activity

    Mark Shaaya, Jordan Fauser ... Andrei V Karginov
    Light-sensitive allosteric switch module, a broadly applicable protein engineering method, is used for the regulation of protein activity with tight temporal control and spatial precision.

    Structural insights into mRNA reading frame regulation by tRNA modification and slippery codon–anticodon pairing

    Eric D Hoffer, Samuel Hong ... Christine M Dunham
    Chemical modifications near the tRNA anticodon and specific mRNA–tRNA pairs combine to control the ribosomal three-nucleotide mRNA reading frame, essential for the sequential addition of amino acids into polypeptide chains.

    A physicochemical perspective of aging from single-cell analysis of pH, macromolecular and organellar crowding in yeast

    Sara N Mouton, David J Thaller ... Liesbeth M Veenhoff
    In mitotically aging yeast cells, the cytosol acidifies, the distances between the organellar membranes decrease dramatically, but crowding on the scale of the average size protein is relatively stable.

    POMK regulates dystroglycan function via LARGE1-mediated elongation of matriglycan

    Ameya S Walimbe, Hidehiko Okuma ... Kevin P Campbell
    Protein O-Mannose Kinase enables Like-acetyl-glucosaminyltransferase 1 to elongate matriglycan on α-dystroglycan, thereby allowing matriglycan to function as a scaffold for extracellular matrix proteins and prevent muscular dystrophy.

    Genome-wide effects of the antimicrobial peptide apidaecin on translation termination in bacteria

    Kyle Mangano, Tanja Florin ... Nora Vázquez-Laslop
    Inhibition of bacterial protein synthesis by an antimicrobial peptide apidaecin triggers translation arrest at the stop codons, ribosome queuing and pervasive stop codon readthrough.
