Journal ArticleDOI
In vivo and in vitro studies of major surface loop deletion mutants of the Escherichia coli K‐12 maltoporin: contribution to maltose and maltooligosaccharide transport and binding
Christian Andersen,Christoph Bachmeyer,Harald Täuber,Roland Benz,Jiang Wang,Valérie Michel,Salete M. C. Newton,Maurice Hofnung,Alain Charbit +8 more
TL;DR: In vivo and in vitro results suggest that maltooligosaccharides enter the LamB channel from the cell surface side with the non‐reducing end in advance, which results in a considerable difference in the on‐rate of carbohydrate binding from the extracellular side compared with that from the periplasmic side.
Journal ArticleDOI
Pores from mitochondrial outer membranes of yeast and a porin-deficient yeast mutant: a comparison.
TL;DR: In this article, the porin-free mitochondrial outer membrane of a yeast mutant was reconstituted with a single-channel conductance of 2.0 nS in 1 M KCl and the characteristics of general diffusion pores with an estimated effective diameter of 1.2 nm.
Journal ArticleDOI
Formation of small transmembrane pores: An intermediate stage on the way to Bacillus cereus non-hemolytic enterotoxin (Nhe) full pores in the absence of NheA.
Kui Zhu,Andrea Didier,Richard Dietrich,Uta Heilkenbrinker,Eva Waltenberger,Nadja Jessberger,Erwin Märtlbauer,Roland Benz +7 more
TL;DR: The NheBC complex itself has a tendency to increase the membrane permeability prior to the emergence of full pores containing also NheA, so the benefit of these complexes is a more stable cell binding as well as stronger and earlier cytotoxic effect.
Journal ArticleDOI
CymA of Klebsiella oxytoca Outer Membrane: Binding of Cyclodextrins and Study of the Current Noise of the Open Channel
Frank Orlik,Christian Andersen,Christophe Danelon,Mathias Winterhalter,Markus Pajatsch,August Böck,Roland Benz +6 more
TL;DR: CymA, the outer membrane component of the cyclodextrin (CD) uptake and metabolism system of Klebsiella oxytoca, was reconstituted into lipid bilayer membranes, and the channel properties of this unusual porin were studied in detail.
Journal ArticleDOI
The BBA01 protein, a member of paralog family 48 from Borrelia burgdorferi, is potentially interchangeable with the channel-forming protein P13.
TL;DR: It is demonstrated that BBA01 is a channel-forming protein with properties surprisingly similar to those of P13, which together with the high degree of sequence similarity suggests that the two proteins may have similar and interchangeable functions.
