Yellow fever is an acute viral disease caused by Yellow fever virus. It has a high morbidity and mortality of global importance with an annual incidence rate of 200,000 infections and death toll of over 30,000. It is imperative to restrict the spread of this disease and to prevent huge human and economic losses. So far, no treatment or cure exists for yellow fever, there is great interest in developing strategies to control the disease. The viral genome encodes many proteins out of which, the E protein is involved in initiation of infection. We performed the comparative modeling and docking analysis of envelop gene (1YFE) from yellow fever virus. Homologous sequences were searched for the query 1YFE), Based on high sequence similarity and lowest E-value, the envelope protein of dengue fever virus (3G7T) was chosen as template. Homology modeling was performed using “EasyModeller 4.0”. The model was assessed by program “Procheck” and ProSA” web server resulting in 0.7% disallowed residues and Z score -6.18 respectively. ‘Moe’ was used for the superposition of the protein structure with the template and the superposed model was then subjected to ligand interaction analysis using Ds viewer. The docking of drugs was performed using docking server. In short, this study can be a good initiative towards finding a good cure for the unchecked yellow fever infections with global applicability.
