Information on the related virus
The recombinant plasmid has been generated by replacing in frame the original HIV-1 protease gene of NL4-3 with the entire protease gene taken from HIV-2 ROD. The resulting plasmid expresses, upon transfection of human cells, all viral proteins but failed to produce infectious particles in experimental cell infections in vitro.
