Rifampicin
Rifamycin
- Inhibits initiation of RNA synthesis
- Blocks formation of first phosphodiester bond
Actinomycin D
- Inhibits RNA synthesis by incalating DNA
- Causes mutations
- Works in both pro- and eukaryotes
Alpha-amanitin
- Inihibits eukaryotic RNA polymerase
- RNA pol I - (nucleolus) insensitive
- RNA pol II - (mRNA) highly sensitive
- RNA pol III - (tRNA) moderately sensitive
Antibiotics to bacteria
- Inhibit protein translation
- Act of rRNA, not the ribosomal protein
Diphtheria toxin
