At present, many specific detection methods and inhibitors of β‐lactamase have been developed and applied in clinical practice. In this Minireview, we describe the resistance mechanism of bacteria producing β‐lactamase and further summarize the fluorogenic probes, inhibitors of β‐lactamase, and their applications in the treatment of infectious diseases.

The bacteria then become resistant to the antibiotics. Beta-lactamase enzymes are produced by certain strains of the following bacteria: Bacteroides species, Enterococcus species, Hemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae, and Staphylococcus species, either constitutively or on exposure to antimicrobials. β-Lactam antibiotics are the most commonly used antibacterial agents and growing resistance to these drugs is a concern. Metallo-β-lactamases are a diverse set of enzymes that catalyze the hydrolysis of a broad range of β-lactam drugs including carbapenems. This diversity is reflected in the observa … Beta-lactamases are a family of enzymes involved in bacterial resistance to beta-lactam antibiotics. They act by breaking the beta-lactam ring that allows penicillin-like antibiotics to work.

Beta-lactamases are enzymes 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 provides antibiotic resistance by breaking the antibiotics' structure. These antibiotics all have a common element in their molecular structure: a four-atom ring known as a β-lactam. Through hydrolysis, the enzyme lactamase breaks

The metallo-beta-lactamase protein fold is a protein domain contained in class B beta-lactamases and a number of other proteins. These proteins include thiolesterases, members of the glyoxalase II family, that catalyse the hydrolysis of S-D-lactoyl-glutathione to form glutathione and D-lactic acid and a competence protein that is essential for natural transformation in Neisseria gonorrhoeae

The bactericidal mechanism of killing by β-lactams is perceived to be a major advantage in the treatment of serious infections. When these agents were threatened by the rapid emergence of β-lactamases, β-lactamase-stable agents were developed, as well as potent β-lactamase inhibitors (BLIs). Extended-spectrum beta-lactamases are specific enzymes released by a bacteria that neutralizes the effects of antibiotics. 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.

The nucleotide sequences of all β-lactamase genes, including those encoding for Ambler class A, B, C, and D β-lactamases, were obtained from the GenBank nucleotide database, and the high-throughput sequencing reads were mapped to the reference sequences of the β-lactamase genes as previously described .
