+== Publication Abstract from PubMed ==
+Biapenem is a parenteral carbapenem antibiotic that exhibits wide-ranging antibacterial activity, remarkable chemical stability, and extensive stability against human renal dehydropeptidase-I. Tebipenem is the active form of tebipenem pivoxil, a novel oral carbapenem antibiotic that has a high level of bioavailability in humans, in addition to the above-mentioned features. beta-lactam antibiotics, including carbapenems, target penicillin-binding proteins (PBPs), which are membrane-associated enzymes that play essential roles in peptidoglycan biosynthesis. To envisage the binding of carbapenems to PBPs, we determined the crystal structures of the trypsin-digested forms of both PBP 2X and PBP 1A from Streptococcus pneumoniae strain R6, each complexed with biapenem or tebipenem. The structures of the complexes revealed that the carbapenem C-2 side chains form hydrophobic interactions with Trp374 and Thr526 of PBP 2X and with Trp411 and Thr543 of PBP 1A. The Trp and Thr residues are conserved in PBP 2B. These results suggest that interactions between the C-2 side chains of carbapenems and the conserved Trp and Thr residues in PBPs play important roles in the binding of carbapenems to PBPs.
