the basis for carbapenem hydrolysis by class a β-lactamases: a combined investigation using crystallography and simulations.carbapenems are the most potent β-lactam antibiotics and key drugs for treating infections by gram-negative bacteria. in such organisms, β-lactam resistance arises principally from β-lactamase production. although carbapenems escape the activity of most β-lactamases, due in the class a enzymes to slow deacylation of the covalent acylenzyme intermediate, carbapenem-hydrolyzing class a β-lactamases are now disseminating in clinically relevant bacteria. the reasons why carbapenems are substrates fo ...201223030300
