It is one of the two major components of the antibacterial drug virginiamycin, produced by Streptomyces virginiae, S. loidensis, S. mitakaensis, S. pristina-spiralis, S. ostreogriseus, and others. It has a role as an antibacterial drug and a bacterial metabolite. It is a cyclodepsipeptide and a macrolide antibiotic."}]
