Extended spectrum β-lactamases (ESBLs) confer bacterial resistance to third-generation cephalosporins, such as cefotaxime and ceftazidime, increasing hospital mortality rates. Whereas these...
Structure, Function, and Inhibition along the Reaction Coordinate of CTX-M β-Lactamases
Chen, Yu, Shoichet, Brian, Bonnet, Richard
CTX-M enzymes are an emerging group of extended spectrum β-lactamases (ESBLs) that hydrolyze not only the penicillins but also the first-, second-, and third-generation cephalosporins. Although they...
CMT-Type β-Lactamase TEM-125, an Emerging Problem for Extended-Spectrum β-Lactamase Detection†
