    Critical role for isoprenoids in apicoplast biogenesis by malaria parasites

    Megan Okada, Krithika Rajaram ... Paul A Sigala
    Malaria parasites target a polyprenyl synthase enzyme to the apicoplast organelle and require its activity to produce long-chain linear isoprenoids necessary for apicoplast biogenesis.

    Coagulation factors directly cleave SARS-CoV-2 spike and enhance viral entry

    Edward R Kastenhuber, Marisa Mercadante ... Lewis Cantley
    Factor Xa and thrombin cleavage activate SARS-CoV-2 spike, widening the scope of host proteases involved in coronavirus entry and demonstrating the potential for dual anticoagulant/antiviral drugs.

    MicroRNA 3′-compensatory pairing occurs through two binding modes, with affinity shaped by nucleotide identity and position

    Sean E McGeary, Namita Bisaria ... David P Bartel
    Affinity measurements of microRNA sites representing >1000 different pairing architectures reveal that two binding modes can mediate pairing to the microRNA 3′ region, and that microRNA G and oligo(G/C) residues are most impactful.

    Rolling circle RNA synthesis catalyzed by RNA

    Emil Laust Kristoffersen, Matthew Burman ... Philipp Holliger
    All steps of a viroid-like replication cycle can be catalyzed by RNA alone.

    A coarse-grained NADH redox model enables inference of subcellular metabolic fluxes from fluorescence lifetime imaging

    Xingbo Yang, Gloria Ha, Daniel J Needleman
    Mitochondrial metabolic fluxes display a subcellular spatial gradient within a single mouse oocyte, and the fluxes are not controlled by nutrient supply or energy demand of the cell, but by the intrinsic rates of mitochondrial respiration.

    Structural basis for an unprecedented enzymatic alkylation in cylindrocyclophane biosynthesis

    Nathaniel R Braffman, Terry B Ruskoski ... Emily P Balskus
    The X-ray crystal structure of the unusual carbon–carbon bond-forming biosynthetic enzyme CylK reveals a unique biochemical strategy for selective alkyl halide activation and substitution.

    Aggregation pheromone 4-vinylanisole promotes the synchrony of sexual maturation in female locusts

    Dafeng Chen, Li Hou ... Xianhui Wang
    4-Vinylanisole acts as maturation-accelerating pheromone to synchronize oocyte maturation of female adults in locusts.

    Cellular assays identify barriers impeding iron-sulfur enzyme activity in a non-native prokaryotic host

    Francesca D'Angelo, Elena Fernández-Fueyo ... Gregory Bokinsky
    The intracellular network that distributes iron-sulfur clusters in bacteria is surprisingly 'plug and play' with iron-sulfur enzymes acquired from distantly related species, whereas the intracellular electron transfer network often needs plug adapters to connect with foreign enzymes.

    SWI/SNF senses carbon starvation with a pH-sensitive low-complexity sequence

    J Ignacio Gutierrez, Gregory P Brittingham ... Liam J Holt
    A combination of single-cell analysis, genomics, and simulations shows that a glutamine-rich low-complexity sequence in the SWI/SNF chromatin remodeling complex senses transient intracellular acidification as a signal for cells to switch their global transcriptional program.

    Pyruvate:ferredoxin oxidoreductase and low abundant ferredoxins support aerobic photomixotrophic growth in cyanobacteria

    Yingying Wang, Xi Chen ... Kirstin Gutekunst
    Synechocystis switches its redox pools under reducing photomixotrophic conditions from utilizing NAD(H)- to ferredoxin-dependent enzymes and thereby balances its metabolism in a trade-off between energy conservation and chemical driving forces.
