BLAD ß-Lactmase Database
A comprehensive database of widely circulated ß-Lactamases
Welcome to ß-Lactamase
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.
IMP beta-lactamase (Class B) 
IMP-type carbapenemases (one of the metallo--lactamases)Plasmid-mediated IMP-type carbapenemases, 17 varieties of which are currently known, became established in Japan in the 1990s both in enteric Gram-negative organisms and in Pseudomonas and Acinetobacter species. IMP enzymes spread slowly to other countries in the Far East, were reported from Europe in 1997, and have been found in Canada and Brazil.

About ß-Lactamase?
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.
