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

Endonucleolytic cleavage to 5'-phosphomonoester.

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

Post-translational modification

Specific enzymatic cleavages in vivo yield mature proteins.

Miscellaneous

This protein is synthesized as a Gag-Pol polyprotein.

Sequence similarities

Belongs to the retroviral Pol polyprotein family.

Contains 1 integrase catalytic domain.

Contains 1 peptidase A2 domain.

Contains 1 reverse transcriptase domain.

Contains 1 RNase H domain.

Sequence caution

The sequence AAB03091.1 differs from that shown. Reason: Erroneous initiation.
