title: Voltage gating in porin channels.
abstract: Data from experiments in which porin channels are reconstituted into planar bilayer membranes are reviewed for their relevance to porin channel gating in vivo. Contradictory evidence concerning voltage gating indicates that the different results may stem from the variety of purification techniques employed. The likelihood of voltage gating as a property of E. coli porins in vivo is discussed in relation to the possible magnitude of the membrane potential across the outer membrane.
