Does penicillin inhibite protein synthesis

No, penicillin does not inhibit protein synthesis. Instead, it is a beta-lactam antibiotic that disrupts bacterial cell wall synthesis by inhibiting the enzyme transpeptidase, which is essential for cross-linking peptidoglycan layers in the cell wall. This action leads to cell lysis and death in susceptible bacteria. Antibiotics that inhibit protein synthesis, such as tetracyclines and macrolides, target the ribosomal machinery instead.
