Function
function
Oxidized purine nucleoside triphosphate hydrolase which is a prominent sanitizer of the oxidized nucleotide pool. Catalyzes the hydrolysis of 2-oxo-dATP (2-hydroxy-dATP) into 2-oxo-dAMP. Has also a significant hydrolase activity toward 2-oxo-ATP, 8-oxo-dGTP and 8-oxo-dATP. Through the hydrolysis of oxidized purine nucleoside triphosphates, prevents their incorporation into DNA and the subsequent transversions A:T to C:G and G:C to T:A. Also catalyzes the hydrolysis of methylated purine nucleoside triphosphate preventing their integration into DNA. Through this antimutagenic activity protects cells from oxidative stress.
Catalytic activity
- 2-oxo-ATP + H2O = 2-oxo-AMP + diphosphate + H+This reaction proceeds in the forward direction.
- 8-oxo-dATP + H2O = 8-oxo-dAMP + diphosphate + H+This reaction proceeds in the forward direction.
- 8-oxo-dGTP + H2O = 8-oxo-dGMP + diphosphate + H+This reaction proceeds in the forward direction.
- N6-methyl-ATP + H2O = N6-methyl-AMP + diphosphate + H+This reaction proceeds in the forward direction.
- N6-methyl-dATP + H2O = N6-methyl-dAMP + diphosphate + H+This reaction proceeds in the forward direction.
- O6-methyl-dGTP + H2O = O6-methyl-dGMP + diphosphate + H+This reaction proceeds in the forward direction.
