Abstract
Although the crystal structure of DEN2 NS3 serine protease has been reported, the proteolytic mechanism of this enzyme in the presence of NS28 as co-factor which greatly enhances its activity is not well-understood. Using the homology model of DEN2 NS3 co-co rnplexed with NS2 8 co factor based on HCV NS3/4A as the proposed template, the model of the DEN2 NS28 /3 complex was reproduced and its structure evaluated through PROCHECK, VERIFY3D and ERRAT. Comparison of the homology model with the crystal structure of DEN2 NS3 revea led that this homology model served as a better choice for the NS28/3 protein model in drug design.
