    Peptidoglycan-tethered and free forms of the Braun lipoprotein are in dynamic equilibrium in Escherichia coli

    Yucheng Liang, Jean-Emmanuel Hugonnet ... Michel Arthur
    The Braun lipoprotein is tethered to peptidoglycan independently from the insertion of newly-synthesized peptidoglycan subunits into the expanding cell wall generating a dynamic equilibrium between free and bound protein forms.

    Characterization of the ABC methionine transporter from Neisseria meningitidis reveals that lipidated MetQ is required for interaction

    Naima G Sharaf, Mona Shahgholi ... Douglas C Rees
    NmMetQ is a lipoprotein that tethers to membranes via a lipid anchor and has dual function and localization, playing a role in NmMetNI-mediated transport at the inner membrane and moonlighting on the bacterial surface.

    Formation of a β-barrel membrane protein is catalyzed by the interior surface of the assembly machine protein BamA

    James Lee, David Tomasek ... Daniel Kahne
    Outer membrane β-barrel proteins in Gram-negative bacteria are assembled within the lumen of the BamA β-barrel.

    Factors essential for L,D-transpeptidase-mediated peptidoglycan cross-linking and β-lactam resistance in Escherichia coli

    Jean-Emmanuel Hugonnet, Dominique Mengin-Lecreulx ... Michel Arthur
    Production of the L,D-transpeptidase YcbB and elevated synthesis of the (p)ppGpp alarmone reveals a new mode of peptidoglycan polymerization that bypasses the D,D-transpeptidase activity of PBPs and leads to broad-spectrum β-lactam resistance in Escherichia coli.

    Novel adverse outcome pathways revealed by chemical genetics in a developing marine fish

    Elin Sørhus, John P Incardona ... Sissel Jentoft
    Global gene expression analysis unravels the underlying mechanisms for distinct crude oil induced defects in Atlantic haddock eggs and larvae.

    Coordination of peptidoglycan synthesis and outer membrane constriction during Escherichia coli cell division

    Andrew N Gray, Alexander JF Egan ... Waldemar Vollmer
    The protein CpoB regulates PBP1B activity in response to the Tol energy state, which facilitates feedback and synchronicity between envelope constriction processes during Gram-negative bacterial cell division.

    Identification of a bilirubin receptor that may mediate a component of cholestatic itch

    James Meixiong, Chirag Vasavda ... Xinzhong Dong
    MRGPRX4 is a bilirubin receptor that may be a therapeutic target for patients suffering from cholestatic itch.

    Identification of orphan ligand-receptor relationships using a cell-based CRISPRa enrichment screening platform

    Dirk H Siepe, Lukas T Henneberg ... K Christopher Garcia
    A proteo-genomic CRISPR activation screening workflow to accelerate the identification of novel interactions between the secreted and membrane proteome with the potential to define new biological processes and identify future therapeutic targets.

    Heavy isotope labeling and mass spectrometry reveal unexpected remodeling of bacterial cell wall expansion in response to drugs

    Heiner Atze, Yucheng Liang ... Michel Arthur
    Labeling with 13C and 15N in the absence of metabolic engineering enabled the exploration of peptidoglycan metabolism at a very fine level of detail based on kinetic characterization of isotopologues predicted to occur according to known recycling and biosynthesis pathways.

    Cytosolic aggregation of mitochondrial proteins disrupts cellular homeostasis by stimulating the aggregation of other proteins

    Urszula Nowicka, Piotr Chroscicki ... Agnieszka Chacinska
    Defective mitochondrial protein import results in protein aggregation and a specific chaperone response in the cytosol, causatively linking mitochondrial function and cellular protein homeostasis disturbances observed in neurodegeneration.
