SUMMARY Since the introduction of penicillin, β-lactam antibiotics have been the antimicrobial agents of choice. Unfortunately, the efficacy of these life-saving antibiotics is significantly threatened by bacterial β-lactamases. β-Lactamases are now responsible for resistance to penicillins, extended-spectrum cephalosporins, monobactams, and carbapenems. In order to overcome β-lactamase

The test disk employed consists of a chromogenic cephalosporin which is used as the substrate. the production of beta-lactamase. The Cefinase disc is impregnated with the chromogenic cephalosporin, Nitrocefin. This compound exhibits a very rapid colour change from yellow to red as the amide bond in the beta lactam ring is hydrolyzed by a beta-lactamase.

The appearance of superbugs producing metallo-beta-lactamases have resulted in a clinical crisis. This project intends to express and purify subclasses of 

Some germs, such as Escherichia coli (E. coli) and Klebsiella, produce an enzyme called extended spectrum beta-lactamase (ESBL). This enzyme makes the germ harder to treat with antibiotics.

Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates (tazobactam and sulbactam) which ultimately leads to the degradation of the beta-lactamase. Avibactam on the other hand does not contain a beta-lactam ring (non beta-lactam beta-lactamase inhibitor), and instead binds reversibly.

*Please select more than one item to compare. 36 matches found for beta lactamase. Beta-lactamase -producing bacteria (BLPB) can play an important role in polymicrobial infections. They can have a direct pathogenic impact in causing the infection as well as an indirect effect through their ability to produce the enzyme β-lactamase. BLPB may not only survive penicillin therapy but can also, as was demonstrated in in vitro and in Beta-lactamases are enzymes produced by bacteria that provide multi-resistance to β-lactam antibiotics such as penicillins, cephalosporins, cephamycins, and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase.

The encoded protein has some sequence similarity to prokaryotic beta-lactamases but most of the residues that are responsible for the beta-lactamase activity are … A beta-lactam antibiotic produced by the actinobacterium Streptomyces clavuligerus.
