Negative Impact of Carbapenem Methylation on the Reactivity of β-Lactams for Cysteine Acylation as Revealed by Quantum Calculations and Kinetic Analyses
The Enterococcus faecium l,d-transpeptidase (Ldt(fm)) mediates resistance to most β-lactam antibiotics in this bacterium by replacing classical peptidoglycan polymerases. The catalytic Cys of Ldt(fm) is rapidly acylated by β-lactams belonging to the carbapenem class but not by penams or cephems. We...
