EC Tree
     3 Hydrolases
         3.6 Acting on acid anhydrides
             3.6.1 In phosphorus-containing anhydrides
                3.6.1.55 8-oxo-dGTP diphosphatase
IUBMB Comments
This enzyme hydrolyses 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 hydrolyse 2-hydroxy-dATP (cf. EC 3.6.1.56, 2-hydroxy-dATP diphosphatase) . Requires Mg2+.
