Rifampin inhibits the bacterial ribosome by complexing with the beta-subunit encoded by the rpoB gene. Resistance to rifampin is mediated by specific mutations in the beta-subunit of the rRNA polymerase or less commonly by drug inactivation and drug binding.
- Rifampin ADP-ribosyltransferase Arr
- Rifampin glycosyltransferase
- Rifampin phosphotransferase
- Rifampin-resistant beta-subunit of RNA polymerase RpoB
- RNA-polymerase binding protein
