Penicillin G sodium is a cornerstone antibiotic of beta lactam class. It works by specifically binding to and inhibiting D-alanyl-D-alanine carboxypeptidase, an enzyme that is critical to the formation of peptidoglycan, which gives bacterial cells rigidity and protection. This prevents the bacteria from synthesizing their cell wall, which results in lysis or death.
