WebFeb 17, 2015 · There are four known ways of resistance to β -lactam antibiotics: i) production of β -lactamase enzymes that hydrolyse the β -lactam ring of the antibiotic, ii) penicillin binding proteins that maintain the peptidoglycan structure in bacterial cell wall, iii) alteration of porin channels, and iv) initiation of efflux exporter proteins [ 7, 8 ]. WebTo investigate the preference of CTX-M enzymes for cephalosporins, we examined eleven active-site residues in the CTX-M-14 β-lactamase model system by alanine mutagenesis to assess the contribution of the residues to catalysis and specificity for the hydrolysis of the penicillin, ampicillin, and the cephalosporins cephalothin and cefotaxime.
