ENZYME entry: EC 3.6.1.55

Accepted Name
8-oxo-dGTP diphosphatase.
Alternative Name(s)
7,8-dihydro-8-oxo-dGTP pyrophosphohydrolase.
7,8-dihydro-8-oxoguanine triphosphatase.
8-oxo-dGTPase.
Reaction catalysed
8-oxo-dGTP + H(2)O <=> 8-oxo-dGMP + diphosphate
Cofactor(s)
Magnesium.
Comment(s)
  • This enzyme hydrolyzes the phosphoanhydride bond between the alpha and beta phosphate of 8-oxoguanine-containing nucleoside di- and triphosphates thereby preventing misincorporation of the oxidized purine nucleoside triphosphates into DNA.
  • It does not hydrolyze 2-hydroxy-dATP (cf. EC 3.6.1.56).
