General description

β-Lactamase produced by bacteria shares sequence homology to penicillin-binding proteins.[1] This enzyme is found in Gram-negative bacteria.[2] β-Lactamases have four molecular classes, named A, B, C, and D. A, C, and D form an acyl-enzyme via active site serine residue. Class B β-lactamases are metalloenzymes, which have a zinc ion at their active site for β-lactam hydrolysis.[3]

Biochem/physiol Actions

β-Lactamase hydrolyzes β-lactum antibiotics and is the chief cause of resistance to β-lactam antibiotics development by bacteria.[1][3] Mutations in the β-lactamases are associated with extended-spectrum β-lactamases (ESBLs).[4]

Preparation Note

Following reconstitution, store in the refrigerator (4°C). Stock solutions are stable for up to 1 month at 4°C.

Other Notes

One unit is defined as the amount of enzyme that will hydrolyze 1.0 µmol benzyl penicillin and 1.0 µmol of cephalosporin C, respectively, per min at 25°C.

Sibhghatulla Shaikh et al.
Saudi journal of biological sciences, 22(1), 90-101 (2015-01-07)
Antibiotic resistance is a problem of deep scientific concern both in hospital and community settings. Rapid detection in clinical laboratories is essential for the judicious recognition of antimicrobial resistant organisms. Production of extended-spectrum β-lactamases (ESBLs) is a significant resistance-mechanism that
Karen Bush et al.

Two classification schemes for beta-lactamases are currently in use. The molecular classification is based on the amino acid sequence and divides beta-lactamases into class A, C, and D enzymes which utilize serine for beta-lactam hydrolysis and class B metalloenzymes which
Karen Bush

β-Lactamases, the major resistance determinant for β-lactam antibiotics in Gram-negative bacteria, are ancient enzymes whose origins can be traced back millions of years ago. These well-studied enzymes, currently numbering almost 2,800 unique proteins, initially emerged from environmental sources, most likely
