Benzylpenicillin 3d structure

Benzylpenicillin 3d structure. Benzyl features a benzene ring ( C 6 H 6 ) attached to a methylene group ( −CH 2 − ) group. Tyr105 interacts with an intact ring‐closed penicillin molecule within the active site and is clearly involved in substrate recognition and binding. Penicillin is effective against infections caused by gram-positive cocci, gram-positive rods, most anaerobes, and gram-negative cocci, and it stands as a cornerstone in the management and treatment of various infections within the β-lactam antibiotic class of drugs. Recently, a readily transferable antibiotic resistance factor called the New Delhi metallo-β-lactamase-1 (NDM-1) has been found to confer enteric bacteria resistance to nearly all β-lactams, including the heralded carbapenems, posing a serious threat to human health.
