LACTB, His

SYNONYMS
Beta-lactamase, Cephalosporinase, ampC, ampA, b4150, JW4111.

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.

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.
