Enzyme Information
| 3.6.1.58 |
8-oxo-dGDP phosphatase.
based on mapping to UniProt Q6ZVK8
8-oxo-dGDP + H(2)O = 8-oxo-dGMP + phosphate.
-!- The enzyme catalyzes the hydrolysis of both 8-oxo-dGDP and 8-oxo-GDP thereby preventing translational errors caused by oxidative damage. -!- The preferred in vivo substrate is not known. -!- The enzyme does not degrade 8-oxo-dGTP and 8-oxo-GTP to the monophosphates (cf. EC 3.6.1.55). -!- Ribonucleotide diphosphates and deoxyribonucleotide diphosphates are hydrolyzed with broad specificity. -!- The bifunctional enzyme NUDT5 also hydrolyzes ADP-ribose to AMP and D-ribose 5-phosphate (cf. EC 3.6.1.13). -!- The human enzyme NUDT18 also hydrolyzes 8-oxo-dADP and 2-hydroxy- dADP, the latter at a slower rate.
