Oscillation phenomena in black lipid membranes induced by a single alamethicin pore.
In this paper we  show how alamethicin (a small cyclic peptide of molecular weight 1691) can produce voltage oscillations in black lipid membranes and how a nonactin-alamethicin oscillator can be constructed. Alamethicin alone induces oscillations only with an applied bias current, but with nonactin and appropriate salt solutions oscillations occur with no bias current. Both kinds of oscillations can be quantitatively understood in terms of the known properties of alamethicin and nonactin and both depend on the statistical nature of the formation opores in the membrane by alamethicin.
