A beta-lactam antibiotic produced by the actinobacterium Streptomyces clavuligerus. It is a suicide inhibitor of bacterial beta-lactamase enzymes. Administered alone, it has only weak antibacterial activity against most organisms, but given in combination with other beta-lactam antibiotics it prevents antibiotic inactivation by microbial lactamase.

Endogenous substances and drugs that inhibit or block the activity of BETA-LACTAMASES. Bétalaktamáza (ali β-laktamáza) je predstavnik skupine encimov, ki hidrolizirajo betalaktam v penicilinih in cefalosporinih in jih s tem inaktivirajo. Sintetizirajo jih proti tem antibiotikom odporne bakterije.. Navzkrižna odpornost med penicilini in cefalosporini ni popolna, saj nekatere betalaktamaze izkazujejo večjo afiniteto za peniciline, nekatere pa za cefalosporine.

These antibiotics all have a common element in their molecular structure: a four-atom ring known as a β-lactam. Through hydrolysis, the lactamase enzyme breaks the β-lactam ring open, deactivating the molecule's antibacterial properties.

The enzyme prevents certain antibiotics from being able to kill the bacteria. The bacteria then become resistant to the antibiotics. This means stronger antibiotics must be used to kill the bacteria. Various bacteria produce a class of enzymes called beta-lactamases, which may be mediated by genes on plasmids or chromosomes. Production of beta-lactamase may be constitutive or induced by exposure to antimicrobials. Beta-lactamases are enzymes that open the beta-lactam ring, inactivating the antibiotic.

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 , although carbapenems are relatively resistant to beta-lactamase.

Beta-Lactamase Test rapidly detects the presence of beta-lactamase enzyme produced by strains of Staphylococcus aureus, Neisseria gonorrhoeae, Branhamella catarrhalis and Haemophilus influenzae. These enzymes Beta lactamases can be classified in two ways: Ambler’s classification (structural or molecular classification). Bush Jacoby Medeiros classification or functional (phenotypic)—Advanced and complex classification. Ambler classification of beta-lactamases To detect the enzyme beta-lactamase, which confers penicillin resistance to various bacterial organisms.

coli) and Klebsiella, produce an enzyme called extended spectrum beta-lactamase (ESBL). This enzyme makes the germ harder to treat with antibiotics. ESBL can cause a variety of illnesses, including: Extended Spectrum Beta-Lactamase (ESBL) is an enzyme made by some bacteria.
