The dimer is formed by a stacked beta-interface comprising strands 2, 3, and 4, with the two triple-stranded antiparallel beta-sheets, one from each subunit, oriented antiparallel to each other. One surface of the dimer, bounded by the loop between strands beta 1 and beta 2, forms a saddle-shaped groove with dimensions of approximately 24 x 23 x 12 A in cross section. Lys264, which has been shown from mutational data to be involved in DNA binding, protrudes from this surface, implicating the saddle-shaped groove as the potential DNA binding site. | The solution structure of the DNA binding domain of HIV-1 integrase (residues 220-270) has been determined by multidimensional NMR spectroscopy.

FunctionPOL_HV1Z6 Integrase performs the integration of the newly synthesized dsDNA copy of the viral genome into the host chromosome. The integrated DNA is called provirus. Publication Abstract from PubMedThe solution structure of the DNA binding domain of HIV-1 integrase (residues 220-270) has been determined by multidimensional NMR spectroscopy. The protein is a dimer in solution, and each subunit is composed of a five-stranded beta-barrel with a topology very similar to that of the SH3 domain.
