Energetic, structural, and antimicrobial analyses of beta-lactam side chain recognition by beta-lactamases.
Chem.Biol., 8:17-31, 2001

PubMed Abstract: Penicillins and cephalosporins are among the most widely used and successful antibiotics. The emergence of resistance to these beta-lactams, most often through bacterial expression of beta-lactamases, threatens public health. To understand how beta-lactamases recognize their substrates, it would be helpful to know their binding energies. Unfortunately, these have been difficult to measure because beta-lactams form covalent adducts with beta-lactamases. This has complicated functional analyses and inhibitor design.
