β‑lactam antibiotics exert their antibacterial effect by
interfering with cell wall biosynthesis, leading to loss of structural
integrity and cell death in actively dividing bacteria. Structural studies show
that these drugs covalently interact with enzymes responsible for peptidoglycan
cross‑linking.

Based on this mode of action, β‑lactam antibiotics most plausibly function by
mimicking which native bacterial structure?
