Outer Membrane Vesicles Released From Aeromonas Strains Are Involved in the Biofilm Formation

open access: yesFrontiers in Microbiology, 2021
Aeromonas spp. are Gram-negative rod-shaped bacteria ubiquitously distributed in diverse water sources. Several Aeromonas spp. are known as human and fish pathogens.

The antimicrobial peptide Magainin-2 interacts with BamA impairing folding of E. coli membrane proteins

open access: yesFrontiers in Chemistry, 2022
Antimicrobial peptides (AMPs) are a unique and diverse group of molecules endowed with a broad spectrum of antibiotics properties that are being considered as new alternative therapeutic agents.

Protein-protein interactions and the spatiotemporal dynamics of bacterial outer membrane proteins.

open access: yesCurr Opin Struct Biol, 2015
It has until recently been unclear whether outer membrane proteins (OMPs) of Gram-negative bacteria are organized or distributed randomly. Studies now suggest promiscuous protein-protein interactions (PPIs) between β-barrel OMPs in Escherichia coli govern their local and global dynamics, engender spatiotemporal patterning of the outer membrane into ...

Selective pressure for rapid membrane integration constrains the sequence of bacterial outer membrane proteins. [PDF]

open access: yesMol Microbiol, 2017
SummaryAlmost all bacterial outer membrane proteins (OMPs) contain a β barrel domain that serves as a membrane anchor, but the assembly and quality control of these proteins are poorly understood. Here, we show that the introduction of a single lipid‐facing arginine residue near the middle of the β barrel of the Escherichia coli OMPs OmpLA and EspP ...

Subdominant antigens in bacterial vaccines: AM779 is subdominant in the Anaplasma marginale outer membrane vaccine but does not associate with protective immunity. [PDF]

open access: yesPLoS ONE, 2012
Identification of specific antigens responsible for the ability of complex immunogens to induce protection is a major goal in development of bacterial vaccines.

Omp85, an evolutionarily conserved bacterial protein involved in outer-membrane-protein assembly

open access: bronzeResearch in Microbiology, 2003
The insertion of proteins into membranes generally requires the assistance of membrane proteins. A protein, designated Omp85 in Neisseria meningitidis, was shown to be required for the assembly of bacterial outer-membrane proteins. The protein is essential for the viability of the bacteria and is ubiquitous among Gram-negative bacteria. Omp85 depletion

Pattern of amino acid substitutions in transmembrane domains of β-barrel membrane proteins for detecting remote homologs in bacteria and mitochondria. [PDF]

open access: yesPLoS ONE, 2011
β-barrel membrane proteins play an important role in controlling the exchange and transport of ions and organic molecules across bacterial and mitochondrial outer membranes.

Solute channels of the outer membrane: from bacteria to chloroplasts [PDF]

open access: yes, 2007
Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding

Super-Resolution Imaging of Protein Secretion Systems and the Cell Surface of Gram-Negative Bacteria

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Gram-negative bacteria have a highly evolved cell wall with two membranes composed of complex arrays of integral and peripheral proteins, as well as phospholipids and glycolipids.
