• Name the protein synthesis inhibiting antibiotics that act by:
1- binding of 50S subunit to the 30S subunit (ribosome assembly)
2- irreversible binding to 30S subunit leading to misreading of mRNA
3- binding to 30S subunit at the A-site preventing binding of new tRNA
4- binding to 50S subunit of the ribosome and inhibits the bacterial enzyme
peptidyl transferase.
5- binding to 50S subunit of the ribosome at the P-site of the 50S ribosomal
subunit inhibiting the transfer of the peptidyl tRNA (from A to P site)
