Binding Target  Integrase

Mechanism  Two viral encoded enzymes(reverse transcriptase and integrase) play central roles in the early stages of the replication of retroviruses and retrotransposons.The peptide derived from the RT DNA polymerase domain inhibits all three integrase-associated activities (3′-end processing, strand transfer, and disintegration) and inhibit virus replication.
