Abstract

Hepatitis E is a form of liver disease characterized by inflammation of the liver due to infection with the Hepatitis E virus, whose structure is not present in PDB so structure prediction is important to stop the virus in future. The FASTA sequence of the ORF-1 Polyprotein of HEV was retrieved from NCBI (NCBI Reference Sequence: NP_056779.1), which does not show any transmembrane proteins in their structure. The best quality templates were taken from HHpred server. Then with the help of MODELLER, it was generated 3 models which were further refined and validated by using SAVS (Structural analysis and verification server) with validation programme like Procheck for getting the best model with high Ramachandran plot score value. The best model obtained was model_3 (6197496_pdb), which is having a maximum Ramachandran score of 92.2 per cent, of the residues and had an average 3D-ID score > 0.2.
