Folding of a monomeric porin, OmpG, in detergent solution.

Abstract excerpt

OmpG, a porin from E. coli, has been examined in planar lipid bilayers and in detergent solution. First, bilayer recordings were used to reinforce the evidence that the functional form of OmpG is a monomer. Both pH-dependent gating and blockade by covalent modification add support to this proposal. The findings contrast with the properties of the classical porins, which function as trimers. Second, the folding of...
