ASV INTEGRASE CORE DOMAIN WITH HIV-1 INTEGRASE INHIBITOR Y3 AND MN CATION
Overview
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 ...
