Abstract
Human cells infected with a recombinant vaccinia virus containing human immunodeficiency virus type 1 gag-pol genes produced large amounts of human immunodeficiency virus gag proteins beginning at 1 h and peaking at 48 h postinfection. We show that these polyproteins are processed accurately into mature forms and that the viral polymerase gene is encoded as a 160-kilodalton gag-pol fusion protein, most likely by translational frameshifting from the gag into the pol reading frame.
