CACODYLATED CATALYTIC DOMAIN OF HIV-1 INTEGRASE
OverviewOverview
Human immunodeficiency virus (HIV) integrase is the enzyme responsible for insertion of a DNA copy of the viral genome into host DNA, an essential step in the replication cycle of HIV. HIV-1 integrase comprises three functional and structural domains: an N-terminal zinc-binding domain, a catalytic core domain and a C-terminal DNA-binding domain. The catalytic core domain with the F185H mutation has been crystallized without sodium cacodylate in a new crystal form, free and complexed with the catalytic metal Mg2+. The structures have been determined and refined to about 2.2 A. Unlike the previously reported structures, the three active-site carboxylate residues (D,D-35-E motif) are well ordered and both aspartate residues delineate a proper metal-binding site. Comparison of the active binding site of this domain with that of other members from the polynucleotidyl transferases superfamily shows a high level of similarity, providing a confident template for the design of antiviral agents.
