CC -!- FUNCTION: During replicative cycle of retroviruses, the reverse-
CC transcribed viral DNA is integrated into the host chromosome by the
CC viral integrase enzyme. RNase H activity is associated with the reverse
CC transcriptase. {ECO:0000256|ARBA:ARBA00023429}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3'-end directed exonucleolytic cleavage of viral RNA-DNA
CC hybrid.; EC=3.1.13.2; Evidence={ECO:0000256|ARBA:ARBA00000379};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of RNA in RNA/DNA hybrids. Three different
CC cleavage modes: 1. sequence-specific internal cleavage of RNA. Human
CC immunodeficiency virus type 1 and Moloney murine leukemia virus
CC enzymes prefer to cleave the RNA strand one nucleotide away from the
CC RNA-DNA junction. 2. RNA 5'-end directed cleavage 13-19 nucleotides
CC from the RNA end. 3. DNA 3'-end directed cleavage 15-20 nucleotides
CC away from the primer terminus.; EC=3.1.26.13;
CC Evidence={ECO:0000256|ARBA:ARBA00023415};
CC -!- SIMILARITY: Belongs to the retroviral Pol polyprotein family.
CC {ECO:0000256|ARBA:ARBA00009555, ECO:0000256|RuleBase:RU004064}.
