Penicillin binding proteins (PBPs) possess transpeptidase, transglycosylase as well as carboxypeptidase activities and mediates the crosslinking of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM) of peptidoglycan, thereby promoting the cell wall synthesis. The β-lactam antibiotics bind to PBPs and inactivate them, thus killing the bacteria. During the course of evolution, bacteria have also developed differential survival strategies. Emergence of multidrug resistance resulting from β-lactamases constitutes a worldwide threat. This enzyme hydrolyzes β-lactam antibiotics and thus makes them inactive. The purpose of this study was to analyze the binding affinity of β-lactam antibiotics with PBPs and β-lactamases by computational docking studies. For this, different classes of β-lactams know..
