What is Valinomycin?

Plain description, key identifiers and synonyms

Valinomycin is a twelve-membered cyclodepsipeptide composed of three repeating D-alpha-hydroxyisovaleryl-D-valyl-L-lactoyl-L-valyl units joined in sequence. An antibiotic found in several Streptomyces strains. It has a role as an antiviral agent, an antimicrobial agent, a bacterial metabolite and a potassium ionophore. It is a cyclodepsipeptide and a macrocycle.
