pristinamycin usage and synthesis |
usage | an antibiotic used in livestock feed to prevent disease among young swine. also is used in ethanol production to prevent microbial contamination. |
usage |
virginiamycin complex is defined as a mixture of 75% ostreogrycin a (virginiamycin m1) and 25% virginiamycin s1, together with the less abundant s analogues. as the two major components have quite different solubilities, these proportions are not readily achieved or used. bioaustralis has isolated and re-combined the individual components to provide the defined components of virginiamycin complex. the composition of the complex is important as virginiamycin s1 acts a synergist, binding to the conformational change of the peptidyl transferase centre of the 50s ribosome induced by ostreogrycin a. |
