One of the main causes of resistance to β-lactam drugs is caused by β-lactamases. Chemically, β-lactamases bind to β-lactams the same way β-lactams bind to PBPs. However, the β-lactamases are then able to deactivate the antimicrobial activity of the β-lactams by cleaving the β-lactam bound in the active site through a molecular process called deacylation, rendering it incapable of inhibiting the PBPs and ultimately, allowing cross-linking to occur for adequate cell wall formation. | One of the main causes of resistance to β-lactam drugs is caused by β-lactamases.
