Increased salt concentration promotes competitive block of OmpF channel by protons
Elsevier (2012-11)Porins are channel-forming proteins that are located in the outer membranes (OM) of Gram-negative bacteria and allow the influx of hydrophilic nutrients and the extrusion of waste products. The fine regulation of the ion ... -
Linearity, saturation and blocking in a large multiionic channel: divalent cation modulation of the OmpF porin conductance
Elsevier (2011-01)Measurement of unitary conductance is a fundamental step in the characterization of a protein ion channelpermeabilizing a membrane. We study here the effect of salts of divalent cations on the OmpF channelconductance ...
