Abstract: White spot syndrome virus (WSSV), the main causative agent of white spot disease (WSD), is prevalent in aquatic crustaceans but exhibits the most virulent effects in penaeid shrimps. A highly ubiquitous interaction takes place between the viral envelope protein VP28 of WSSV and Rab7 of Penaeus monodon which helps WSSV to escape from the late endosomal vesicle before it becomes too acidic for it to survive. Through in-sillico molecular docking analysis we identified that some residues of the effector loop of Rab7 play a major role in its interaction with VP28. Three bioactive molecules were identified by computational analysis in AutoDock Vina which target the effector loop or residues interacting with it and thus might hinder the escape route of WSSV leading to reduction of the virulence of the virus.
