Journal ArticleDOI
An RND-type efflux system in Borrelia burgdorferi is involved in virulence and resistance to antimicrobial compounds.
TL;DR: It is shown that BesC, a TolC homolog, forms channels in planar lipid bilayers and is involved in antibiotic resistance, signifying the importance of this outer membrane channel in the mammalian host.
Journal ArticleDOI
A water-soluble form of porin from the mitochondrial outer membrane of Neurospora crassa. Properties and relationship to the biosynthetic precursor form.
TL;DR: Water-soluble porin was shown to be able to bound mitochondria in the presence of detergents and converted into a water-solubilized form as discussed by the authors.
Journal ArticleDOI
Characterization of the channel formed by the mycobacterial porin in lipid bilayer membranes. Demonstration of voltage gating and of negative point charges at the channel mouth.
Joaquim Trias,Roland Benz +1 more
TL;DR: Identical channels were observed when membranes were reconstituted with cell wall extracts, suggesting that there is only one porin species in the mycobacterial cell wall, and the channel was cation-selective and had 2.5-point negative charges at both sides of the channel.
Journal ArticleDOI
Cholesterol-dependent pore formation of Clostridium difficile toxin A.
TL;DR: Data indicate that in colonic cells toxin A induces pore formation in an acidic environment similar to that reported for toxin B and suggest that pore Formation by clostridial glucosylating toxins depends on the presence of cholesterol.
Journal ArticleDOI
Porins from plants. Molecular cloning and functional characterization of two new members of the porin family.
Karsten Fischer,Andreas P.M. Weber,Susanne Brink,Bettina Arbinger,Danja Schünemann,S Borchert,H W Heldt,Birgit Popp,Roland Benz,T A Link +9 more
TL;DR: It is concluded that mitochondria and non-green plastids possess homologous porin proteins, whereas chloroplasts are characterized by a different type of porin.
