Beta-lactamases are enzymes (EC 3.5.2.6) produced by bacteria that provide multi- resistance to β-lactam antibiotics such as penicillins, cephalosporins, cephamycins, and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase.

Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates (tazobactam and sulbactam) which ultimately leads to the degradation of the beta-lactamase. Beta-laktamaza (EC 3.5.2.6, penicilinaza, cefalosporinaza, neutrapen, penicilinska beta-laktamaza, eksopenicilinaza, ampicillinaza, penicilin amido-beta-laktamhidrolaza, penicilinaza I, II, beta-laktamaza I-III, beta-laktamaza A, B, C, beta-laktamaza AME I, cefalosporin-beta-laktamaza) je enzim sa sistematskim imenom beta-laktam hidrolaza. A beta-lactam (β-lactam) ring is a four-membered lactam. A lactam is a cyclic amide, and beta -lactams are named so because the nitrogen atom is attached to the β-carbon atom relative to the carbonyl. Beta-lactamase-producing bacteria (BLPB) can play an important role in polymicrobial infections.They can have a direct pathogenic impact in causing the infection as well as an indirect effect through their ability to produce the enzyme β-lactamase.

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 is a common chemical structure to all beta-lactam antibiotics.

This gene encodes a mitochondrially-localized protein that has sequence similarity to prokaryotic beta-lactamases. Many of the residues responsible for beta-lactamase activity are not conserved in this protein, suggesting it may have a different enzymatic function. Increased expression of the related mouse gene was found to be associated View protein in PROSITE PS00146, BETA_LACTAMASE_A, 1 hit PS51257, PROKAR_LIPOPROTEIN,

This section displays by default the canonical protein sequence and upon request all isoforms described in the entry. Beta Lactamase detection Beta-laktam ili β-laktamski prsten je četveročlani laktam. Laktam je ciklični amid, koji je tako nazvan zato što mu je atom dušika vezan za β-ugljik, u odnosu na karbonil.

Subsequently, a closely related enzyme was discovered and named TEM-2.
