    Assigning mitochondrial localization of dual localized proteins using a yeast Bi-Genomic Mitochondrial-Split-GFP

    Gaétan Bader, Ludovic Enkler ... Hubert Dominique Becker
    The Bi-Genomic Mitochondrial-Split-GFP, where both fragments of the Split-GFP are expressed by separated translation machineries, shuts off cytosolic fluorescence of dual-localized proteins, allowing visualization of their mitochondrial echoforms.

    Mechanism of chiral proofreading during translation of the genetic code

    Sadeem Ahmad, Satya Brata Routh ... Rajan Sankaranarayanan
    Structural biology has elucidated the mechanism of a configuration-specific enzyme that decouples D-amino acids from the translational machinery and, therefore, is involved in the enforcement of homochirality during protein synthesis.

    Ternatin and improved synthetic variants kill cancer cells by targeting the elongation factor-1A ternary complex

    Jordan D Carelli, Steven G Sethofer ... Jack Taunton
    An ancient complex comprising the eukaryotic elongation factor-1A and aminoacylated tRNA is shown to be the target of a cyclic heptapeptide and two unrelated natural products with potent anticancer activity.

    A translation proofreader of archaeal origin imparts multi-aldehyde stress tolerance to land plants

    Pradeep Kumar, Ankit Roy ... Rajan Sankaranarayanan
    Genetic, biochemical, and bioinformatic analyses reveal how expanding metabolic repertoire interferes with fundamental processes like protein synthesis inside cells and the role of D-aminoacyl-tRNA deacylase2 in protecting these processes during terrestrialisation.

    An optimal regulation of fluxes dictates microbial growth in and out of steady state

    Griffin Chure, Jonas Cremer
    Microbial cells optimally structure their proteomes in order to mutually maximize metabolism and translation, as established by an extensive comparison between data and a low-dimensional model of cellular physiology.
