Outer membrane vesicles (blebs) are produced by Escherichia coli , Salmonella , and all other gram-negative bacteria both in vitro and in vivo. Most of the research in the field has focused on the properties of vesicles derived from pathogenic bacteria and their interactions with eukaryotic ...

Outer membrane protein evolution
Current Opinion in Structural Biology, 2021Outer membrane proteins have remarkably homogeneous structure. They are all up down β-barrels. Up down barrels themselves are composed of repeated sets of β-hairpins. The consistency of the usage of the β-hairpin throughout the outer membrane milieu allows for interrogation of the evolution of these repetitive structures.

Cracking outer membrane biogenesis
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2023The outer membrane is a distinguishing feature of the Gram-negative envelope. It lies on the external face of the peptidoglycan sacculus and forms a robust permeability barrier that protects extracytoplasmic structures from environmental insults. Overcoming the barrier imposed by the outer membrane presents a significant hurdle towards developing novel

The transport of small molecules across membranes is essential for the import of nutrients and other energy sources into the cell and, for the export of waste and other potentially harmful byproducts out of the cell. While hydrophobic molecules are permeable to membranes, ions and other small polar molecules require transport via specialized membrane ...

Folding of outer membrane proteins
Archives of Biochemistry and Biophysics, 2013Outer membrane proteins (OMPs) represent a large group of β-barrel proteins found both in the membranes of both bacteria and eukaryotes. Their general ease of expression and refolding and straightforward methods to monitor their degree of folding conspire to make OMPs excellent model systems to investigate how the membrane environment and other ...

Assembling the mitochondrial outer membrane
Nature Structural & Molecular Biology, 2004The general preprotein translocase of the outer mitochondrial membrane (TOM complex) transports virtually all mitochondrial precursor proteins, but cannot assemble outer-membrane precursors into functional complexes. A recently discovered sorting and assembly machinery (SAM complex) is essential for integration and assembly of outer-membrane proteins ...

Comparison of Chlamydia outer membrane complex to recombinant outer membrane proteins as vaccine
Vaccine, 2020The Chlamydial outer membrane complex (COMC) from the elementary body (EB) is a protein rich insoluble outer membrane shell from which cytosolic proteins have been extracted with detergent. In this study we conducted mass spectrometry experiments to detect proteins in the COMC prepared from C. muridarum EB.

Permeability of the Outer Membrane of Bacteria
Angewandte Chemie International Edition in English, 1979AbstractThe outer membrane of Gram‐negative bacteria is an attractive system for the study of the structure‐function relationships in biological membranes. This membrane has, inter alia, the task of regulating the inflow of nutrients and outflow of waste products.
