It is a monomeric protein that requires no metals or cofactors for activity. TEM-1 beta-lactamase efficiently hydrolyzes most penicillin and cephalosporin substrates, including n 2021-02-04 2020-04-21 Beta-lactamases are enzymes that open the beta-lactam ring, inactivating the antibiotic. The first plasmid-mediated beta-lactamase in gram-negative bacteria was discovered in Greece in the 1960s. It was named TEM after the patient from whom it was isolated (Temoniera) .

Beta-lactam antibiotics are used to treat a variety of bacterial infections and are among the most prescribed drugs in the US. Beta-lactamase inhibitors are drugs that are co-administered with beta-lactam antibiotics to prevent antibiotic resistance by inhibiting serine beta-lactamases, which are enzymes that inactivate the beta-lactam ring, which Beta-lactamases cleave the beta-lactam ring of susceptible penicillins and cephalosporins, inactivating the antibiotic. Some antimicrobials (eg, cefazolin and cloxacillin) are naturally resistant to certain beta-lactamases.

Se hela listan på folkhalsomyndigheten.se Beta-lactamases are a family of enzymes involved in bacterial resistance to beta-lactam antibiotics. They act by breaking the beta-lactam ring that allows penicillin-like antibiotics to work. Strategies for combating this form of resistance have included the development of new beta-lactam antibiotics that are more resistant to cleavage and the development of the class of enzyme inhibitors called beta-lactamase inhibitors.
