Valinomycin is a cyclododecadepsipeptide potassium-selective ionophore antibiotic that is isolated from various strains of Streptomyces. The hydrophilic interior is the right size to accommodate the potassium ion, but not other ions, while the hydrophobic exterior allows the complex to pass through the lipid...

A potassium ionophore that is well known to cause the collapse of the mitochondrial membrane potential, which preceeds cytoplasmic acidification, cysteine-active-site protease activation, DNA fragmentation and apoptotic cell death.

Valinomycin is a cyclododecadepsipeptide antibiotic originially isolated from Streptomyces strains and displays antibacterial efficacy. Valinomycin a neutral ionophore that selectively transfers alkali metal ions via biological and synthetic lipid membranes. Valinomycin is widely used as a selective potassium...
