An Extended Reservoir of Class-D Beta-Lactamases in Non-Clinical Bacterial Strains [PDF]
Bacterial genes coding for antibiotic resistance represent a major issue in the fight against bacterial pathogens. Among those, genes encoding beta-lactamases target penicillin and related compounds such as carbapenems, which are critical for human ...

Exploiting the aggregation propensity of beta-lactamases to design inhibitors that induce enzyme misfolding [PDF]
There is an arms race between beta-lactam antibiotics development and co-evolving beta-lactamases, which provide resistance by breaking down beta-lactam rings.

Extended-Spectrum Beta-Lactamases [PDF]
The definition of extended-spectrum beta-lactamases (ESBLs) has expanded rapidly, in terms of both the number and the variety of enzymes. Bacteria bearing plasmidic ESBLs are spreading widely throughout the world.

Novel Computational Protocols for Functionally Classifying and Characterising Serine Beta-Lactamases. [PDF]
Beta-lactamases represent the main bacterial mechanism of resistance to beta-lactam antibiotics and are a significant challenge to modern medicine. We have developed an automated classification and analysis protocol that exploits structure- and sequence ...

Peptidase activity of beta-lactamases. [PDF]
Although beta-lactamases have generally been considered as being devoid of peptidase activity, a low but significant hydrolysis of various N-acylated dipeptides was observed with representatives of each class of beta-lactamases. The kcat/Km values were below 0.1 M(-1).

The OXA β-lactamases were among the earliest β-lactamases detected; however, these molecular class D β-lactamases were originally relatively rare and always plasmid mediated.

Docking Study for New 7-Aminocephalosporinic Acid Derivatives as Potential Inhibitors for β-Lactamases [PDF]
Background: Antibiotics with β-Lactam rings (β-Lactams), since they were discovered, have enhanced the typical treatment for bacterial infections.
