Porin and porin-associated protein (PAP) of Rhodospirillum rubrum FR1

Microbiology, 1995
The porin of Rhodospirillum rubrum FR1 was found in the outer membrane as a complex with a relatively small (32 kDa) porin-associated protein (PAP). The porin moiety of the complex consisted of a trimer which revealed a mainly β-sheet structure, while the porin-PAP complex also contained a significant α-helical portion.

Porins in the Cell Wall of Mycobacteria

Science, 1992
The cell wall of mycobacteria is an efficient permeability barrier that makes mycobacteria naturally resistant to most antibiotics. Liposome swelling assays and planar bilayer experiments were used to investigate the diffusion process of hydrophilic molecules through the cell wall of Mycobacterium chelonae and ...

A light-triggered transmembrane porin

Chemical Communications, 2018
Porins are ideal model systems for channel engineering. Here, we present a photocaged diethylaminocoumarin (DEACM) hybrid of the transmembrane porin OmpG.

Biophysics of the structure and function of porins

Quarterly Reviews of Biophysics, 1990
Gram-negative bacteria such asEscherichia coli(E. coli) andSalmonella typhimurium(S. typhimurium) have two layers of membranes in the cellular envelope – the cytoplasmic membrane and the outer membrane (Fig. I). Between these membranes is a periplasmic space in which there is a peptidoglycan layer that provides the cells with mechanical rigidity.

The biogenesis and function of eukaryotic porins

Experientia, 1990
Like most other mitochondrial proteins porin is synthesized in the cytosol and imported posttranslationally into the outer mitochondrial membrane. This transport follows the general rules for mitochondrial protein import with a few aberrations: a) porin contains an uncleaved NH2-terminal signal sequence, b) also its carboxyterminus might be involved in

Novel Aspects of the Electrophysiology of Mitochondrial Porin

Biochemical and Biophysical Research Communications, 1998
The recent findings that mitochondrial porin, VDAC, participates in supramolecular complexes and is present in the plasmamembrane need to be reconciled with its biophysical properties. We report here that VDAC often displays previously unobserved or unappreciated behaviors.

Prokaryotic and eukaryotic porins

Current Opinion in Structural Biology, 1991
Porins form water-filled, voltage-controlled channels across bacterial outer membranes. The trimeric protein resides within the hydrophobic membrane domain with unusual stability despite its hydrophilicity. Its channels are formed by β-barrels (one per monomer) that consist of single antiparallel pleated sheets.
