10.5 EXTRACTION OF GENES AND SCREENING OF DRUGS              255




                  We collected all the necessary information for our ten selected genes along with their three-
               dimensional structures from the protein data bank (PDB). The PDB contains the protein structural
               information obtained from XRD crystallography, nuclear magnetic resonance spectroscopy, and the-
               oretical modeling [46]. The lists of all the reported drugs were downloaded from the drug bank database
               for the ten target proteins. Table 10.3 shows the list of drugs for each protein. Drug bank 1.0, released in
               2006, was updated to Drug bank 4.0 in 2014 [48].
