What antibotic inhibits the crossing of the peptidoglycan?

Penicillin is an antibiotic that inhibits the synthesis of peptidoglycan, a crucial component of bacterial cell walls. It does this by targeting and inhibiting the enzyme transpeptidase, which is essential for cross-linking the peptidoglycan layers. This disruption weakens the bacterial cell wall, ultimately leading to cell lysis and death, particularly in actively dividing bacteria. Other beta-lactam antibiotics also share this mechanism of action.
