The Cys-rich domain, core region and basic domain are highly conserved and very important to the trans-activation activity of HIV-1 Tat trans-activator. The three-dimensional structures of 6 mutants of HIV-1 Tat protein were constructed with the methods of molecular dynamics simulation. The variations of the structures of the mutants have been analyzed and the factors that led to abolishment of trans-activation activity have been discussed.
