Penicillin is a widely used antibiotic prescribed to treat staphylococci and streptococci bacterial infections. Penicillin belongs to the beta-lactam family of antibiotics, the members of which use a similar mechanism of action to inhibit bacterial cell growth that eventually kills the bacteria. Bacteria cells are surrounded by a protective envelope called the cell wall.
Mechanism of Action. â¢ Penicillins are dipeptide analogs of D-ala-D-ala. â¢ Radiolabelled Penicillin G binds to several different proteins in the cell wall of bacteria (Table 1). â¢ Bactericidal action is primarily due to inhibition of PBPs 1a & 1b and PBP3 that function as. transpeptidases in the biosynthesis of the peptidoglycan.
