    Divergent folding-mediated epistasis among unstable membrane protein variants

    Laura M Chamness, Charles P Kuntz ... Jonathan P Schlebach
    Many of the synergistic interactions between mutations are modified in the context of unstable proteins in a manner that depends on how the variants promote misfolding in the cell.

    Interactions between a subset of substrate side chains and AAA+ motor pore loops determine grip during protein unfolding

    Tristan A Bell, Tania A Baker, Robert T Sauer
    The AAA+ protein unfolding motor ClpX grips substrates with the uppermost part of its substrate-binding pore, and requires interactions with hydrophobic amino acid side chains to operate with optimal efficiency.

    Intact protein folding in the glutathione-depleted endoplasmic reticulum implicates alternative protein thiol reductants

    Satoshi Tsunoda, Edward Avezov ... David Ron
    Adapting a cytosolic enzyme that breaks down glutathione to function in the lumen of the endoplasmic reticulum challenges the long-held view that reduced glutathione fuels disulfide rearrangements during protein folding.
