Invitrogen™ Beta-Lactamase (TEM-1) Recombinant Protein
Descripción
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 nitrocefin and fluorescent derivates. This protein is intended to be used as a positive control for enzyme-dependent substrate hydrolysis and for use on immunoblots. Other uses include kinetic studies with novel substrates or identification of inhibitors of beta-lactamase as part of an antimicrobial program. 1165 micromoles of penicillin G hydrolyzed per minute per milligram of total protein.
