The x-ray structures of an inhibitor complex of the catalytic core domain of avian sarcoma virus integrase (ASV IN) were solved at 1.9- to 2.0-A resolution at two pH values, with and without Mn2+ cations. This inhibitor (Y-3), originally identified in a screen for inhibitors of the catalytic activity of HIV type 1 integrase (HIV-1 IN), was found in the present study to be active against ASV IN as well as HIV-1 IN. The Y-3 molecule is located in close proximity to the enzyme active site, interacts with the flexible loop, alters loop conformation, and affects the conformations of active site residues. As crystallized, a Y-3 molecule stacks against its symmetry-related mate. Preincubation of IN with metal cations does not prevent inhibition, and Y-3 binding does not prevent binding of divalent cations to IN. Three compounds chemically related to Y-3 also were investigated, but no binding was observed in the crystals. Our results identify the structural elements of the inhibitor that likely determine its binding properties.
