Cofactor: Evidence: Note:
Mg(2+) ECO:0000250
Binds 2 magnesium ions for reverse transcriptase polymerase activity.
Mg(2+) ECO:0000269 | PubMed:22366278
ECO:0000250 | UniProtKB:A1Z651
Binds 2 Mn(2+)/Mg(2+) ions for ribonuclease H (RNase H) activity (PubMed:22366278). Shows 4- to 6-fold increased rates of cleavage in the presence of Mn(2+) versus Mg2(2+) (By similarity).
Mg(2+) ECO:0000250
Magnesium ions are required for integrase activity. Binds at least 1, maybe 2 magnesium ions.
