Virginiamycin Complex Quick inquiry Where to buy Suppliers range | Virginiamycin complex is defined as a mixture of 75% virginamycin M1 (ostreogrycin A) and 25% virginiamycin S1 and the less abundant S analogs. As the two major components have quite different solubilities these proportions are not readily achieved or used. The individual components are isolated and re-combined to provide the defined components of virginiamycin complex. The structure composition of the complex is important as Virginiamycin S1 acts a synergist, binding to the conformational change of the peptidyl transferase center of the 50S ribosome induced by ostreogrycin A. Group: Biochemicals. Alternative Names: Cebin V, Eskalin V, Eskamicin, Stafac, Stephylomycin, Mikamycin, Ostreogrycin, Patricin, Pristinamycin, Streptogramin, Vernamycin. Grades: Highly Purified.

In the 1950s this complex was independently discovered so many times the literature became highly confusing. Ostreogrycin A is a macrocyclic lactone antibiotic that acts syngeristically with the structurally unrelated cyclic depsipeptides more commonly known as the virginiamycins B (ostreogrycin B or streptogramin B) and S to inhibit peptide elongation. This is achieved by blocking formation of a peptide bond between the growing peptide chain (peptidyl-tRNA) linked to the 50S ribosome and aminoacyl-tRNA. Ostreogrycin A has proven to be highly active against Gram positive bacteria, particularly methicillin-resistant S. aureus. Group: Biochemicals.
