Abstract The ATP-independent chaperone SurA protects unfolded outer membrane proteins (OMPs) from aggregation in the periplasm of Gram-negative bacteria, and delivers them to the β-barrel assembly machinery (BAM) for folding into the outer membrane

Abstract Fibrous networks constructed from high aspect ratio protein building blocks are ubiquitous in nature. Despite this ubiquity, the functional advantage of such building blocks over globular proteins is not understood. To answer this question,

The authors of this work characterize the effect of amino acid substitution on α-synuclein (α-Syn) aggregation. Residues 38 and 42 (in addition to 39) within the P1 region of α-Syn affect amyloid formation. The effect of substitution at position 3

Interaction of the outer membrane protein (OMP) chaperone SurA and the OMP folding catalyst BAM results in changes in the conformational ensembles of both species, suggesting a mechanism for delivery of OMPs to BAM in Gram-negative bacteria.

The folding of outer membrane proteins (OMPs) is catalyzed by the βbarrel assembly machinery (BAM). Here, structural and functional analyses of BAM stabilized in distinct conformations elucidate the roles of lateral gate opening and interactions of

With cryo-EM, single-molecule FRET and MD simulations, Iadanza et al. characterise the membrane protein insertase complex BAM in lipid bilayer nanodiscs. They show that the β-barrel domain of BamA is in a ‘lateral open’ conformation, and that BA

The chaperone SurA is involved in outer membrane protein (OMP) biogenesis in Gram-negative bacteria, but its mechanism of action is not fully understood. Combining mass spectrometric, biophysical and computational approaches, the authors here show ho

Protein aggregation remains a significant challenge for manufacturing of protein biopharmaceuticals. Here, the authors demonstrate the use of directed evolution and an assay for in vivo innate protein aggregation-propensity to generate aggregation-re

Through a multi-modal rheology approach, we show that muscle-inspired hydrogels exhibit a surprising diversity of viscoelastic response from power-law rheology at low strains to stiffening and energy dissipation at high strains.
