    Neurotoxin-mediated potent activation of the axon degeneration regulator SARM1

    Andrea Loreto, Carlo Angeletti ... Michael P Coleman
    The identification of the mechanism of action of vacor, an environmental neurotoxin which causes neurodegeneration by activating the pro-degenerative enzyme SARM1, raises important questions on SARM1 as a mediator of environmental neurotoxicity and has implications for drug discovery.

    Systematic investigation of the link between enzyme catalysis and cold adaptation

    Catherine Stark, Teanna Bautista-Leung ... Daniel Herschlag
    Increased catalysis has been suggested to be an adaptive trait of enzymes to growth at lower temperature, but systematic analysis suggests that temperature exerts a weak selection pressure on enzyme rate enhancement, with observed variation arising from other evolutionary forces.

    Directed evolution of the rRNA methylating enzyme Cfr reveals molecular basis of antibiotic resistance

    Kaitlyn Tsai, Vanja Stojković ... Danica Galonić Fujimori
    Directed evolution of the resistance enzyme Cfr under antibiotic selection identifies increased Cfr expression and stability as strategies to boost resistance and reveals that Cfr modification of the ribosome confers resistance by sterically occluding binding of antibiotics.

    Disruption of the TCA cycle reveals an ATF4-dependent integration of redox and amino acid metabolism

    Dylan Gerard Ryan, Ming Yang ... Christian Frezza
    Multi-omic analyses reveal a connection between the integrated stress response and the regulation of redox and amino acid metabolism when the TCA cycle is impaired.

    Structure-guided glyco-engineering of ACE2 for improved potency as soluble SARS-CoV-2 decoy receptor

    Tümay Capraz, Nikolaus F Kienzl ... Johannes Stadlmann
    Molecular dynamics simulation assisted engineering of recombinant soluble human ACE2 N-glycosylation by site-directed mutagenesis or glycosidase treatment yields a superior SARS-CoV-2 decoy receptor.

    Low-affinity integrin states have faster ligand-binding kinetics than the high-affinity state

    Jing Li, Jiabin Yan, Timothy A Springer
    Faster ligand-binding kinetics of integrin low-affinity states suggests that integrin binding to ligand and intracellular adapters and the actin cytoskeleton precedes their stabilization, together with tensile force, of the high-affinity, extended-open integrin conformation.

    Allosteric mechanism of signal transduction in the two-component system histidine kinase PhoQ

    Bruk Mensa, Nicholas F Polizzi ... William F DeGrado
    Mutations along the signaling pathway of the E. coli sensor histidine kinase PhoQ alter signal gain and ligand-sensitivity by altering thermodynamic allosteric coupling between domains.

    Defining the interactome of the human mitochondrial ribosome identifies SMIM4 and TMEM223 as respiratory chain assembly factors

    Sven Dennerlein, Sabine Poerschke ... Peter Rehling
    Definition of the mitoribosome interactome revealed inner membrane proteins and elucidated new assembly factors of the cytochrome c reductase and cytochrome c oxidase.

    A molecular mechanism for the generation of ligand-dependent differential outputs by the epidermal growth factor receptor

    Yongjian Huang, Jana Ognjenovic ... John Kuriyan
    Cryo-EM analysis of full-length human epidermal growth factor receptor provides a molecular explanation for how ligand-induced differential effect in the ligand-binding extracellular module tunes the transmembrane signaling mediated by epidermal growth factor receptor.

    Allosteric ligands control the activation of a class C GPCR heterodimer by acting at the transmembrane interface

    Lei Liu, Zhiran Fan ... Jianfeng Liu
    Functional analysis reveals a distinct mode of action of the allosteric modulators in the GABAB receptor in a pocket that is formed only in the active state and identifies a region in the GABAB2 subunit important for allosteric agonism.
