Despite several attempts to control this disease, the endemicity of food poisoning increases yearly. This study involves structure based drug designing against potential therapeutic targets (Uridylate kinase, D- alanine--D-alanine ligase, Diaminopimelate (DAP) epimerase, 1-deoxy-D- xylulose 5-phosphate reductoisomerase, 3-methyl-2-oxobutanoate hydroxymethyltransferase) of Clostridium botulinum ATCC 3502. Homology modeling enables generation of three dimensional models of target proteins using sequence with maximum similarity as template for backbone generation. Many compounds were screened to identify lead molecules capable of inhibiting target proteins. Molecular docking assists in identifying promising candidates for each drug target with highest binding energy to be considered for drug discovery platform. Further, MD simulation was also performed for to study the mobility and conformation of proteinâ€“ligand complex at various time intervals.
