Prior to integration, two nucleotides are removed from each 3' end of the linear viral DNA, thereby exposing recessed 3' hydroxyls. This reaction may serve to remove heterogenous extra bases from the viral DNA end, and to stabilize the IN-DNA complex. The chemistry of cleavage is a simple hydrolysis by single-step transesterification.
