a four-atom ring known as a betalactam. TEM-1 is the most commonly-encountered beta-lactamase in gram-negative bacteria. Up to 90% of ampicillin resistance inE. coliis due to the production of TEM-1. Also responsible for the ampicillin and penicillin resistance that is seen in H.influenzae...
TEM-1 beta-lactamase is the most widespread enzyme to confer beta-lactam antibiotic resistance to gram-negative bacteria. 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 nit...

TEM-1. Also responsible for the ampicillin and penicillin resistance that is seen in H.influenzae and N.gonorrhoeae in increasing numbers. Based upon different combinations of changes, currently 140 TEM-type enzymes have been described. Recombinant beta-lactamase TEM-1 contains 264 amino acids ...
Beta Lactamase TEM 1 is an enzyme encoded by the bla gene in E. coli, with its expression being constitutive. The resistance to β-lactam antibiotics is directly proportional to the number of copies of the bla gene and the enzyme synthesized. ...
