    The whale shark genome reveals patterns of vertebrate gene family evolution

    Milton Tan et al.
    The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.

    In situ imaging of bacterial outer membrane projections and associated protein complexes using electron cryo-tomography

    Mohammed Kaplan et al.
    Electron cryo-tomography reveals that bacteria can form structurally-diverse outer membrane extensions with various protein complexes associated with them.

    N501Y mutation of spike protein in SARS-CoV-2 strengthens its binding to receptor ACE2

    Fang Tian et al.
    Spike protein of SARS-CoV-2 with mutation N501Y shows a faster association rate, slower dissociation rate, and higher binding probability and unbinding force to its human receptor protein ACE2, leading to higher transmission.

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

    Giulia Bandini et al.
    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 et al.
    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.

    The structure of photosystem I from a high-light-tolerant cyanobacteria

    Zachary Dobson et al.
    The necessity of studying extremophile organisms is exemplified by the structure of photosystem I from a high-light tolerant cyanobacteria, demonstrating the relationship between the structure and function in photosystem I.

    A precisely adjustable, variation-suppressed eukaryotic transcriptional controller to enable genetic discovery

    Asli Azizoglu et al.
    A new gene expression tool enables precise control of protein dosage over a large range and paves the way for new genetic discoveries.

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

    Naima G Sharaf et al.
    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.

    Disintegration promotes protospacer integration by the Cas1-Cas2 complex

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