摘要
An obligatory step of retroviral growth is the integration of a DNA copy of the viral RNA into the genomic DNA of the host. Recombinant human immunodeficiency virus type I (HIV-1) integrase (IN) expressed in Escherichia coli efficiently catalyzes the overall in vitro integration reaction, namely, the processing of the long terminal repeat (LTR) ends and the strand transfer reaction. Using the 3′ end of synthetic oligonucleotides which match the termini of HIV-1 LTRs as substrate and supercoiled pSP65 DNA as the target, we describe an assay that is suitable for the enzymatic analysis of the integration and for testing candidate inhibitors of HIV IN protein. © 1993 Academic Press, Inc.
