1. valinomycin
   A potassium ionophore antibiotic, produced by Streptomyces fulvissimus . Composed of 3 molecules (L-valine, D -a- hydroxyisovaleric acid, L-lactic acid) linked alternately to form a 36-membered ring, that folds to make a cage shaped like a tennis-ball seam. This wraps specifically around potassium ions, presenting them with a hydrophilic interior, and a lipid bilayer with a hydrophobic exterior. Potassium is thus free to diffuse through the lipid bilayer. Highly ion specific, valinomycin is used in ion-selective electrodes.

4. Valinomycin
   `Valinomycin` is a dodecadepsipeptide antibiotic. Valinomycin is obtained from the cells of several Streptomyces strains, among which "S. tsusimaensis" and S. fulvissimus. It is a member of the group of natural neutral ionophores because it does not have a residual cha...
