| umls-concept:C0042287 | skos:definition | MSH: A cyclododecadepsipeptide ionophore antibiotic produced by Streptomyces fulvissimus and related to the enniatins. It is composed of 3 moles each of L-valine, D-alpha-hydroxyisovaleric acid, D-valine, and L-lactic acid linked alternately to form a 36-membered ring. (From Merck Index, 11th ed) Valinomycin is a potassium selective ionophore and is commonly used as a tool in biochemical studies.,NCI: A cyclic depsipeptide isolated from the bacterium Streptomyces fulvissimus. As a potassium-specific ionophore, mould element causes loss of mitochondrial membrane potential, thereby initiating cellular apoptosis. (NCI04) | lld:umls |
