BLAD ß-Lactamase 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.

PDB Analysis tool


The Protein Data Bank (PDB) is a repository for the 3-D structural data of large biological molecules, such as proteins and nucleic acids. The data, typically obtained by X-ray crystallography or NMR spectroscopy and submitted by biologists and biochemists from around the world, are freely accessible on the Internet via the websites of its member organisations. In the present  database user can access  the information about the crystal structures of betalactamases, their variants and amino acids within the active site. Furthermore, they can also access the information about the physiochemical properties of chemical compounds bound within the active site of the target.  This information can be access by clicking the ligand option on summary table.
