<unk>  inhibits cell wall biosynthesis by binding penicillin-binding proteins which stops peptidoglycan synthesis. Penicillin-binding proteins are bacterial proteins that help to catalyze the last stages of peptidoglycan synthesis, which is needed to maintain the cell wall. They remove the D-alanine from the precursor of the peptidoglycan. The lack of synthesis causes the bacteria to lyse because they also continually break down their cell walls.<unk>  is bactericidal, meaning it kills the bacteria rather than inhibiting their growth.
