Impact of remote mutations on metallo-β-lactamase substrate specificity: Implications for the evolution of antibiotic resistance

Metallo-β-lactamases have raised concerns due to their ability to hydrolyze a broad spectrum of β-lactam antibiotics. The G262S point mutation distinguishing the metallo-β-lactamase IMP-1 from IMP-6 has no effect on the hydrolysis of the drugs cephalothin and cefotaxime, but significantly improves c...
