BLAD ß-Lactmase Database
A comprehensive database of widely circulated ß-Lactamases
Welcome to ß-Lactmase
Beta-lactamases are enzymes  produced by some bacteria and are responsible for their resistance to beta-lactam antibiotics like penicillins, cephamycins, and carbapenems (ertapenem) (Cephalosporins are relatively resistant to beta-lactamase). These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam.
CARB beta-lactamase (Class A) 
Carbenicillin is a bacteriolytic antibiotic belonging to the carboxypenicillin subgroup of the penicillins. It was discovered by scientists at Beecham and marketed as Pyopen. It has Gram-negative coverage which includes Pseudomonas aeruginosa but limited Gram-positive coverage. The carboxypenicillins are susceptible to degradation by beta-lactamase enzymes, although they are more resistant than ampicillin to degradation.
About ß-Lactmase?
Beta-lactam antibiotics are typically used to treat a broad spectrum of Gram-negative bacteria. Beta-lactamases produced by Gram-negative organisms are usually secreted.
