IUBMB Comments

This enzyme hydrolyses the phosphoanhydride bond between the α and β 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+.

The enzyme appears in viruses and cellular organisms
