One of the most illustrative examples of this mechanism is the action of Penicillin. Penicillin targets the synthesis of bacterial cell walls. Bacterial cell walls are composed of peptidoglycan, a polymer that provides structural rigidity and prevents the bacterium from bursting due to osmotic pressure. The enzyme transpeptidase is responsible for cross-linking the peptidoglycan chains to strengthen the wall. Penicillin acts as a competitive inhibitor; it binds irreversibly to the active site of transpeptidase. Once the enzyme is blocked, the bacterium cannot maintain its cell wall integrity. Consequently, water enters the cell, and the bacterium lyses and dies. Human cells do not possess cell walls made of peptidoglycan, nor do they utilize the transpeptidase enzyme. Therefore, Penicillin disrupts a pathway specific to prokaryotes, rendering it non-toxic to the human host. Imagine you're on a mission to build a
