Ordered molecular interactions and structural changes must take place withi
n the human immunodeficiency virus type 1 (HIV-1) preintegration complex at
various stages for successful viral replication. We demonstrate both physi
cal and biochemical interactions between HIV-1 reverse transcriptase and in
tegrase enzymes. This interaction may have implications on the in vivo func
tions of the two enzyme; within the HIV-1 replication complex. It may be on
e of the various molecular interactions, which facilitate efficient HIV-1 r
eplication within the target cells. (C) 2000 Federation of European Biochem
