8-oxo-dGTP diphosphatase (EC 3.6.1.55, MutT, 7,8-dihydro-8-oxoguanine triphosphatase, 8-oxo-dGTPase, 7,8-dihydro-8-oxo-dGTP pyrophosphohydrolase) is an enzyme with systematic name 8-oxo-dGTP diphosphohydrolase.[1][2][3][4] This enzyme catalyses the following chemical reaction:
- 8-oxo-dGTP + H2O [math]\displaystyle{ \rightleftharpoons }[/math] 8-oxo-dGMP + diphosphate
This enzyme requires Mg2+.
