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.
Penicillin is a member of a group of drugs known as Î²-lactams because of their characteristic four-membered lactam ring. Define Î²-lactamase. Î²-lactamase is a bacterial enzyme that hydrolyzes the amide bond of the Î²- lactam ring. It is also known as penicillinase.
