The document discusses protein synthesis and degradation. Protein synthesis occurs in the rough endoplasmic reticulum through translation - the process of mRNA being converted to protein with the help of tRNA and ribosomes. The translation process involves initiation, elongation, and termination steps. Protein degradation is carried out by the proteasome. Several inhibitors are listed that target different steps in protein synthesis, some affecting bacteria and eukaryotes, while others only affect one domain. Protein folding is also mentioned.

25. INHIBITOR SPECIFIC EFFECT
Acting only on bacteria
Tetracycline blocks binding of aminoacyl-tRNA to A-site of
ribosome
Streptomycin prevents the transition from initiation complex to
chain-elongating ribosome and also causes
miscoding
Chloramphenicol blocks the peptidyl transferase reaction on
ribosomes
Erythromycin blocks the translocation reaction on ribosomes
Rifamycin blocks initiation of RNA chains by binding to
RNA polymerase (prevents RNA synthesis)
Acting on bacteria and eucaryotes
Puromycin causes the premature release of nascent
polypeptide chains by its addition to growing
chain end
Actinomycin D binds to DNA and blocks the movement of RNA
polymerase (prevents RNA synthesis)
Acting on eucaryotes but not bacteria
Cycloheximide blocks the translocation reaction on ribosomes
Anisomycin blocks the peptidyl transferase reaction on
ribosomes
α-Amanitin blocks mRNA synthesis by binding preferentially
to RNA polymerase II
