摘要
Both HIV-1 integrase (IN) and the central catalytic domain of IN (IN-CCD) catalyze the disintegration reaction in vitro. In this study, IN and IN-CCD proteins were expressed and purified, and a high-throughput format enzyme-linked immunosorbent assay (ELISA) was developed for the disintegration reaction. IN exhibited a marked preference for Mn2+ over Mg2+ as the divalent cation cofactor in disintegration. Baicalein, a known IN inhibitor, was found to be an IN-CCD inhibitor. The assay is sensitive and specific for the study of disintegration reaction as well as for the in vitro identification of antiviral drugs targeting IN, especially targeting IN-CCD.
