    Multivalency transforms SARS-CoV-2 antibodies into ultrapotent neutralizers

    SARS-CoV-2, the virus responsible for COVID-19, has caused a global pandemic. Antibodies can be powerful biotherapeutics to fight viral infections. Here, we use the human apoferritin protomer as a modular subu...

    Structural basis of substrate recognition and thermal protection by a small heat shock protein

    Small heat shock proteins (sHsps) bind unfolding proteins, thereby playing a pivotal role in the maintenance of proteostasis in virtually all living organisms. Structural elucidation of sHsp-substrate complexe...

    Multiple conformations facilitate PilT function in the type IV pilus

    Type IV pilus-like systems are protein complexes that polymerize pilin fibres. They are critical for virulence in many bacterial pathogens. Pilin polymerization and depolymerization are powered by motor ATPase...

    Structure of a functional obligate complex III2IV2 respiratory supercomplex from Mycobacterium smegmatis

    In the mycobacterial electron-transport chain, respiratory complex III passes electrons from menaquinol to complex IV, which in turn reduces oxygen, the terminal acceptor. Electron transfer is coupled to trans...

    Structure of the alternative complex III in a supercomplex with cytochrome oxidase

    Alternative complex III (ACIII) is a key component of the respiratory and/or photosynthetic electron transport chains of many bacteria13. Like complex III (also known as the bc1 complex), ACIII catalyses the oxi...

    Molecular basis of human CD22 function and therapeutic targeting

    CD22 maintains a baseline level of B-cell inhibition to keep humoral immunity in check. As a B-cell-restricted antigen, CD22 is targeted in therapies against dysregulated B cells that cause autoimmune diseases...

    Atomic model for the membrane-embedded VO motor of a eukaryotic V-ATPase

    The structure of the VO subcomplex of yeast V-ATPase, solved by electron cryomicroscopy, reveals a new subunit and suggests a mechanism for the translocation of protons across membranes.

    Structure of the vacuolar-type ATPase from Saccharomyces cerevisiae at 11-Å resolution

    Vacuolar-type ATPases (V-type ATPases) are large integral membrane protein complexes. Their activity acidifies intracellular compartments, and they are regulated by the dissociation of the complex's V1 and VO ...
