Beta-lactamase inhibitors such asclavulanic acid,sulbactam, andtazobactamwere introduced to overcome the actions of beta-lactamases. These inhibitors work by binding to the active site on the beta-lactamase enzyme, thus preventing binding and hydrolysis of the beta-lactamantibiotic.25 ...

Beta-lactamase inhibitors Clavulanic acid (CLV) is a BLA that, despite its own weak antibacterial activity but due to its effective inhibition of beta-lactamase, can be used together with amoxicillin (AX). Allergic reactions to clavulanic acid have also been reported [76,77]. There are no des...
s classification (Ambler et al., 1991;Bush and Jacoby, 2010). This 2be group of enzymes gathers β-lactamases with activity toward broad-spectrum cephalosporins (ceftazidime, cefotaxime, ceftriaxone) and inhibited by β-lactamase inhibitors (tazobactam, clavulanic acid, sulbactam). Several ESBLs ...
Virtually all gram-negative bacteria studied to date produce a chromosomal betalactamase. Thus, it is not surprising that there is a great diversity among these enzymes in substrate profile, susceptibility to inhibitors, genetic control of expression and molecular makeup. Some enzymes have been ...
