 AB    To analyze the association of the human immunodeficiency virus type 1
       integrase (IN) protein with DNA substrates, we applied a shortwave UV
       cross-linking method to the in vitro integration system. Three
       photoadduct bands were detected on sodium dodecyl sulfate-polyacrylamide
       gels. The appearances of these photoadducts were examined with various
       substrates and under several incubation conditions. Our data suggest
       that one of these photoadducts is derived from the sequence- and
       strand-specific bound state of the early phase of the integration
       reaction before the 3' processing reaction. We also show that most of
       the photoadduct complexes are competent for integration even after UV
       irradiation.
