    Functioni

    During replicative cycle of retroviruses, the reverse-transcribed viral DNA is integrated into the host chromosome by the viral integrase enzyme. RNase H activity is associated with the reverse transcriptase.

    Catalytic activityi

    Endonucleolytic cleavage to 5'-phosphomonoester.PROSITE-ProRule annotation
    Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).PROSITE-ProRule annotation
