ANTIBIOTICS INHIBITORS OF CELL WALL SYNTHESIS (Peptidoglycan)

ANTIBIOTICS INHIBITORS OF CELL WALL SYNTHESIS (Peptidoglycan) NAM SYNTHESIS: D-cycloserine mimics D-Alanine, prevents synthesis. SHUTTLE: Bacitracin interferes with C55 lipid shuttle by binding it. TRANSGLYCOSYLATION: Glycopeptides (e.g. Vancomycin) prevents it.
