    An essential, kinetoplastid-specific GDP-Fuc: β-D-Gal α-1,2-fucosyltransferase is located in the mitochondrion of Trypanosoma brucei

    Giulia Bandini, Sebastian Damerow ... Michael AJ Ferguson
    The activity, localization, and essentiality of TbFUT1, together with its ability to complement Leishmania parasites lacking the homologous gene, suggest the presence of an uncommon and conserved mitochondrial fucosylation pathway required for kinetoplastid parasites viability.

    Bipartite binding and partial inhibition links DEPTOR and mTOR in a mutually antagonistic embrace

    Maren Heimhalt, Alex Berndt ... Roger L Williams
    The inhibitory protein DEPTOR make two widely separated interactions with mTOR that are both necessary for its unique partial mTOR inhibition, and DEPTOR is a more potent inhibitor of mutation- or RHEB-activated mTORC1 than basal mTORC1.

    Addressing shortfalls of laboratory HbA1c using a model that incorporates red cell lifespan

    Yongjin Xu, Richard M Bergenstal ... Ramzi A Ajjan
    The person-specific adjusted HbA1c addresses non-glycaemic variation in laboratory HbA1c due to red blood cell lifespan differences, potentially providing a better marker to predict diabetes complications and guide glycaemic management.

    Edge-strand of BepA interacts with immature LptD on the β-barrel assembly machine to direct it to on- and off-pathways

    Ryoji Miyazaki, Tetsuro Watanabe ... Yoshinori Akiyama
    In vivo crosslinking approaches revealed that the edge-strand of Escherichia coli metallopeptidase BepA interacts with an assembly intermediate of β-barrel outer membrane protein LptD on the outer membrane protein translocon for its targeting to degradation or maturation.

    An engineered transcriptional reporter of protein localization identifies regulators of mitochondrial and ER membrane protein trafficking in high-throughput CRISPRi screens

    Robert Coukos, David Yao ... Alice Y Ting
    HiLITR is a molecular reporter of protein localization that enables straightforward, large-scale, fluorescence-activated cell sorting-based discovery of genes that regulate complex cellular processes, such as mitochondrial and ER tail-anchored protein trafficking.

    β-hydroxybutyrate accumulates in the rat heart during low-flow ischaemia with implications for functional recovery

    Ross T Lindsay, Sophie Dieckmann ... Andrew J Murray
    β-Hydroxybutyrate accumulates in the perfused rat heart during ischaemia, driven by flux through both HMGCS and SCOT, with implications for functional recovery.

    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.

    Concerted conformational dynamics and water movements in the ghrelin G protein-coupled receptor

    Maxime Louet, Marina Casiraghi ... Jean-Louis Banères
    A combination of state-of-the-art biochemical, biophysical, and computational methods revealed that water molecules play a central role in signal propagation through G protein-coupled receptors.

    Disintegration promotes protospacer integration by the Cas1-Cas2 complex

    Chien-Hui Ma, Kamyab Javanmardi ... Makkuni Jayaram
    Disintegration, regarded as an abortive side reaction antithetical to DNA transposition, can promote protospacer integration at the CRISPR locus via DNA repair pathways.

    McsB forms a gated kinase chamber to mark aberrant bacterial proteins for degradation

    Bence Hajdusits, Marcin J Suskiewicz ... Tim Clausen
    The McsB kinase is critical for protein quality control in Gram-positive bacteria, assembling a gated phosphorylation chamber during heat-shock conditions to selectively mark misfolded proteins for degradation.
