Physiological Direction:
Specific for a P1 residue that is hydrophobic, and P1' variable, but often Pro. 3.4.23.16 PROSITE-ProRule:PRU00275
-
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. 3.1.26.13 ECO:0000250

3'-end directed exonucleolytic cleavage of viral RNA-DNA hybrid. 3.1.13.2 ECO:0000250

Cofactor: Evidence: Note:
Mg(2+) ECO:0000250
Binds 2 magnesium ions for reverse transcriptase polymerase activity.
Mg(2+) ECO:0000250
Binds 2 magnesium ions for ribonuclease H (RNase H) activity. Substrate-binding is a precondition for magnesium binding.
Mg(2+) ECO:0000250
Magnesium ions are required for integrase activity. Binds at least 1, maybe 2 magnesium ions.
