    Multi-omic analysis of bat versus human fibroblasts reveals altered central metabolism

    N Suhas Jagannathan, Javier Yu Peng Koh ... Lisa Tucker-Kellogg
    To investigate why bats are long-lived and cancer-resistant, multi-omic data from bat and human cells was analyzed using computational flux modeling, suggesting dysregulation of succinate-fumarate dynamics and an ischemic-like basal metabolism in bat cells.

    X-ray structure and enzymatic study of a bacterial NADPH oxidase highlight the activation mechanism of eukaryotic NOX

    Isabelle Petit-Hartlein, Annelise Vermot ... Franck Fieschi
    Detailed molecular characterization of a constitutively active bacterial NADPH oxidase (NOX) provides clues to the activation mechanism required to trigger electron transfer and reactive oxygen species (ROS) production in tightly regulated eukaryotic NOX.

    Guanidine production by plant homoarginine-6-hydroxylases

    Dietmar Funck, Malte Sinn ... Jörg S Hartig
    2-Oxoglutarate and Fe(II)-dependent dioxygenases from clade C23 are the major source of guanidine in plants and release guanidine from arginine or homoarginine by C5 or C6 hydroxylation, respectively.

    Autotrophic growth of Escherichia coli is achieved by a small number of genetic changes

    Roee Ben Nissan, Eliya Milshtein ... Ron Milo
    Achieving autotrophy in E. coli by introducing a small number of genetic changes crosses a milestone in engineering major metabolic transitions and paves a way for sustainable bio-production from CO2.

    Autonomous metabolic reprogramming and oxidative stress characterize endothelial dysfunction in acute myocardial infarction

    Erika Zodda, Olga Tura-Ceide ... Marta Cascante
    Acute myocardial infarction patient-derived endothelial cells display a strong mitochondrial proton coupling with excess ROS production, enhanced glutamine metabolism and a carbon source switch from glucose to glutamine.
