Biogenesis of mitochondrial β‐barrel membrane proteins

FEBS Open Bio
β‐barrel membrane proteins in the mitochondrial outer membrane are crucial for mediating the metabolite exchange between the cytosol and the mitochondrial intermembrane space. In addition, the β‐barrel membrane protein subunit Tom40 of the translocase of

Dynamic remodeling of the plastid envelope membranes – a tool for chloroplast envelope in vivo localizations

Frontiers in Plant Science, 2012
Two envelope membranes delimit plastids, the defining organelles of plant cells. The inner and outer envelope membranes are unique in their protein and lipid composition.

Meningococcal outer membrane protein NhhA triggers apoptosis in macrophages. [PDF]

PLoS ONE, 2012
Phagocytotic cells play a fundamental role in the defense against bacterial pathogens. One mechanism whereby bacteria evade phagocytosis is to produce factors that trigger apoptosis.

Import and Insertion of Proteins into the Mitochondrial Outer Membrane [PDF]

European Journal of Biochemistry, 1995
Nuclear‐encoded proteins destined for insertion into the mitochondrial outer membrane, follow the same general pathway for import as proteins that are translocated to interior compartments within the organelle. This observation is true both for β‐barrel‐type proteins and for proteins that contain hydrophobic α‐helical transmembrane segments.

Imaging and 3D reconstruction of membrane protein complexes by cryo-electron microscopy and single particle analysis [PDF]

, 2006
Cryo-electron microscopy (cryo-EM) in combination with single particle image processing and volume reconstruction is a powerful technology to obtain medium-resolution structures of large protein complexes, which are extremely difficult to crystallize and ...

Solution nuclear magnetic resonance spectroscopy of bacterial outer membrane proteins in natively excreted vesicles using engineered Escherichia coli

MicrobiologyOpen, 2022
Gaining structural information on membrane proteins in their native lipid environment is a long‐standing challenge in molecular biology. Instead, it is common to employ membrane mimetics, which has been shown to affect protein structure, dynamics, and ...

Skp is a multivalent chaperone of outer-membrane proteins [PDF]

Nature Structural & Molecular Biology, 2016
The trimeric chaperone Skp sequesters outer-membrane proteins (OMPs) within a hydrophobic cage, thereby preventing their aggregation during transport across the periplasm in Gram-negative bacteria. Here, we studied the interaction between Escherichia coli Skp and five OMPs of varying size.

The invariant phenylalanine of precursor proteins discloses the importance of Omp85 for protein translocation into cyanelles [PDF]

, 2007
Background Today it is widely accepted that plastids are of cyanobacterial origin. During their evolutionary integration into the metabolic and regulatory networks of the host cell the engulfed cyanobacteria lost their independency.

The TAM, a Translocation and Assembly Module for protein assembly and potential conduit for phospholipid transfer

EMBO Reports
The assembly of β-barrel proteins into the bacterial outer membrane is an essential process enabling the colonization of new environmental niches. The TAM was discovered as a module of the β-barrel protein assembly machinery; it is a heterodimeric ...
