Function and Biology Details
Reactions catalysed:
DNA(n) + a 2'-deoxyribonucleoside 5'-triphosphate = DNA(n+1) +diphosphate.
3'-end directed exonucleolytic cleavage of viral RNA-DNA hybrid.
Endohydrolysis of RNA in RNA/DNA hybrids. Three different cleavage modes:1. sequence-specific internal cleavage of RNA. Human immunodeficiencyvirus type 1 and Moloney murine leukemia virus enzymes prefer to cleavethe RNA strand one nucleotide away from the RNA-DNA junction. 2. RNA5'-end directed cleavage 13-19 nucleotides from the RNA end. 3. DNA3'-end directed cleavage 15-20 nucleotides away from the primer terminus.
Specific for a P1 residue that is hydrophobic, and P1' variable,but often Pro.
