 AB    The mechanism of HIV DNA integration has been studied in vitro, using
       integrase protein purified from recombinant E. coli, and synthetic
       oligonucleotide substrates. Recent studies focus on structure/function
       analysis of integrase, using mutant derivatives of the protein. In
       parallel with these mechanistic studies we have taken two different
       approaches to find inhibitors of integrase: 1. We have further developed
       an assay previously developed by Craigie et al. (1991) and Mueller et
       al. (1994), to test integration activity in a microtiter assay. Our
       assay (Vink et al. 1994), employs a non-radioactive label instead of
       [32P], and is done within a single well of a microtiter plate (without
       transfer steps). This makes it more convenient for large scale screens.
       Recent progress will be presented. 2. We have tested Combinatorial
       Peptide Libraries (Houghten et al., 1991) and found peptides that
       inhibit integrase activity.
