Understanding Voltage Gating of Providencia stuartii Porins at Atomic Level. [PDF]

PLoS Computational Biology, 2015
Bacterial porins are water-filled β-barrel channels that allow translocation of solutes across the outer membrane. They feature a constriction zone, contributed by the plunging of extracellular loop 3 (L3) into the channel lumen.
