Description
Description: Beta Lactamase is an E Coli Recombinant protein produced in E Coli containing 379 amino acids (20-377) and having a molecular mass of 41.8kDa. Beta Lactamase is expressed with a 21 N-terminal His tag.The LACTB is purified by proprietary chromatographic techniques.
Introduction: Beta-lactamase is a type of enzyme (EC 3.5.2.6) produced by some bacteria that is responsible for their resistance to beta-lactam antibiotics like penicillins, cephalosporins, cephamycins and carbapenems. These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam. The lactamase enzyme breaks that ring open, deactivating the molecule''s antibacterial properties
