Protein attributes

Sequence length	1145 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

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.
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 original EMBL accession numbers (M11337 and M14855) assigned to this isolate (isolate Wyoming) have been made secondary to M16575 which is from a different isolate (clone 1365).
