Which antibiotic inhibits the formation of the peptide side chain of NAM?

Question

Quizplus · Accepted Answer

Cycloserine inhibits the formation of the peptide side chain of NAM by blocking the enzyme responsible for the addition of the D-alanine residues to the peptide side chain during bacterial cell wall synthesis. Vancomycin inhibits peptidoglycan synthesis by binding to the terminal D-alanine residue of the peptide side chain. Bacitracin interferes with the dephosphorylation of the lipid carrier, preventing the release of the building block unit. Cephalexin inhibits bacterial cell wall synthesis by interfering with the cross-linking of peptidoglycan.
