WebRifamycin is used to treat of travelers' diarrhea caused by certain bacteria. Rifamycin is in a class of medications called antibiotics. It works by stopping the growth of the bacteria … WebBiochemical Mechanism Rifamycin drugs work by inhibiting RNA polymerase (RNAP) in target bacteria cells. Background of RNA polymerase (RNAP) RNAP synthesizes RNA from DNA. It has multiple subunits, but β and β’ are specifically integral to the mechanism of action for rifamycin drugs. The active site of RNAP is at the interface between β and β’.
