Abstract

Metallo-beta-lactamases are a source of antibiotic resistance, notably due to their ability to hydrolyse carbapenems. This study will provide structural information necessary to understand the catalytic mechanisms of these enzymes. NMR methods will be used (i) to study the binding of the two active-site metal ions in the presence of substrate analogues to enzymes which are activated and inhibited by the binding of the second metal (from A. hydrophila and B. cereus), and (ii) to determine the solution structure of these enzymes in the presence of substrate analogues, with particular reference to the role of a flexible loop near the active site.
