Name: Virginiamycin, >95%
Price: 407.00 USD

- Overview
  - Virginiamycin is a streptogramin, and a mixture of Virginiamycin M1 and Virginiamycin S1. The commercial mixture is 75 % Virginiamycin M1 and 25 % Virginiamycin S1, along with less abundant S analogs. The mixture can be used to reduce contaminating bacteria during yeast fermentation for bioethanol production. Virginiamycin is soluble in DMSO and DMF.

    Background
    
    Virginiamycin inhibits protein synthesis, targeting the 50S ribosome and inducing a conformational change at the peptidyl transferase center. Protein synthesis is inhibited in both actively growing and static bacterial cells.
