PubMed Abstract: Carbapenem-resistant Enterobacteriaceae are resistant to most β-lactam antibiotics due to the production of the Klebsiella pneumoniae carbapenemase (KPC-2) class A β-lactamase. Here, we present the first product complex crystal structures of KPC-2 with β-lactam antibiotics containing hydrolyzed cefotaxime and faropenem. They provide experimental insights into substrate recognition by KPC-2 and its unique cephalosporinase/carbapenemase activity. These structures also represent the first product complexes for a wild-type serine β-lactamase, elucidating the product release mechanism of these enzymes in general.
