Biophysics of gating phenomena in voltage-dependent OmpC mutant porin channels (R74C and R37C) of Escherichia coli outer membranes
The mechanism by which the membrane potential closes and opens voltage-dependent β-barrel membrane channels is not fully understood. OmpC porins form trimeric water-filled channels when incorporated into arti...

The cytotoxic domain of colicin E9 is a channel-forming endonuclease
Bacterial toxins commonly translocate cytotoxic enzymes into cells using channel-forming subunits or domains as conduits. Here we demonstrate that the small cytotoxic endonuclease domain from the bacterial tox...
