Electroporation of the photosynthetic membrane: structural changes in protein and lipid-protein domains

Abstract: A biological membrane undergoes a reversible permeability increase through structural changes in the lipid domain when exposed to high external electric fields. The present study shows the occurrence of electric field-induced changes in the conductance of the proton channel of the H(+)-ATPase as well as electric field-induced structural changes in the lipid-protein domain of photosystem (PS) II in the photosynthetic membrane. The study was carried out by analyzing the electric field-stimulated delayed luminesc… Show more

“…Mathematical prediction of the three-state model for the lifetime of electropermeabilization (Teissié and Rols, 1994) The long-lived electropermeabilized state implies that proteins are involved in cell membrane electropermeabilization. This is supported by experiments (Teissié and Tsong, 1980;Rosemberg et al, 1994). The field effect was modeled by a three-state scheme: the intact membrane (state A) is brought to a highly unstable state B by the pulse; B is spontaneously converted to the metastable state C:…”

“…Such changes may be caused by lipid-protein interactions (Woolf and Roux, 1994). These interactions could stabilize or destabilize the membrane, and the nature of the interaction may be changed if the proteins undergo electric field-induced changes (Chen and Lee, 1994;Rosemberg et al, 1994). Membrane proteins could also alter the electric field across the bilayer.…”
