Reconstitution of bacterial outer membrane TonB-dependent transporters in planar lipid bilayer membranes.
Micronutrients such as siderophore-bound iron and vitamin B(12) cross the outer membrane of gram-negative bacteria through a group of 22-stranded beta-barrel proteins. They share the unusual feature that their N-terminal end inserts from the periplasmic side into the beta-barrel and plugs the lumen. Transport results from energy-driven movement of TonB protein, which either pulls the plug out o...
متن کاملSignal transduction pathway of TonB-dependent transporters.
Transcription of the ferric citrate import system is regulated by ferric citrate binding to the outer membrane transporter FecA. A signal indicating transporter occupancy is relayed across the outer membrane to energy-transducing and regulatory proteins embedded in the cytoplasmic membrane. Because transcriptional activation is not coupled to ferric citrate import, an allosteric mechanism under...
متن کاملTonB-Dependent Transporters Expressed by Neisseria gonorrhoeae
Neisseria gonorrhoeae causes the common sexually transmitted infection, gonorrhea. This microorganism is an obligate human pathogen, existing nowhere in nature except in association with humans. For growth and proliferation, N. gonorrhoeae requires iron and must acquire this nutrient from within its host. The gonococcus is well-adapted for growth in diverse niches within the human body because ...
متن کاملSodium Channels in Planar Lipid Bilayers
Single channel currents of sodium channels purified from rat brain and reconstituted into planar lipid bilayers were recorded . The kinetics of channel gating were investigated in the presence of batrachotoxin to eliminate inactivation and an analysis was conducted on membranes with a single active channel at any given time . Channel opening is favored by depolarization and is strongly voltage ...
متن کاملWater Permeability of Asymmetric Planar Lipid Bilayers
To understand how plasma membranes may limit water flux, we have modeled the apical membrane of MDCK type 1 cells. Previous experiments demonstrated that liposomes designed to mimic the inner and outer leaflet of this membrane exhibited 18-fold lower water permeation for outer leaflet lipids than inner leaflet lipids (Hill, W.G., and M.L. Zeidel. 2000. J. Biol. Chem. 275:30176-30185), confirmin...
