- Virginiamycin S1 is a main component of virginiamycin preparations. Virginiamycin S1 is one of a family of depsipeptide antibiotic co-produced with ostreogrycin A and used as a synergistic mixture. Virginiamycin S1 also known as Staphylomycin S and Factor S, among other synonyms were discovered independently and named by several groups leading to considerable confusion in the literature. Virginiamycin S1 acts a synergist binding to the conformational change induced by ostreogrycin A of the peptidyl transferase centre of the 50S ribosome. Virginiamycin S1 differs from virginiamycin B in lacking the dimethylamino moiety on the phenyl ring.
