Photoelectric signals of membrane proteins

Principal Investigators: András Dér, Lajos Keszthelyi, Pál Ormos, György Váró,

We discovered that the purple membrane fragments can be oriented in electric field (because the membrane fragments have a large permanent electric dipole moment, due to the fact that the Bacteriorhodopsin molecules are perfectly oriented in them).
