General annotation (Comments)

Function

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 activity

Endohydrolysis of RNA in RNA/DNA hybrids. Three different cleavage modes: 1. sequence-specific internal cleavage of RNA. Human immunodeficiency virus type 1 and Moloney murine leukemia virus enzymes prefer to cleave the RNA strand one nucleotide away from the RNA-DNA junction. 2. RNA 5'-end directed cleavage 13-19 nucleotides from the RNA end. 3. DNA 3'-end directed cleavage 15-20 nucleotides away from the primer terminus.

3'-end directed exonucleolytic cleavage of viral RNA-DNA hybrid.

dUTP + H2O = dUMP + diphosphate.

Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).

Post-translational modification

Cleavage sites that yield the mature proteins remain to be determined.

Sequence similarities

Belongs to the retroviral Pol polyprotein family.

Contains 1 integrase catalytic domain.

Contains 1 integrase-type DNA-binding domain.

Contains 1 integrase-type zinc finger.

Contains 1 peptidase A2 domain.

Contains 1 reverse transcriptase domain.

Contains 1 RNase H domain.

Caution

The N-terminus of the polypeptide is uncertain.
