FunFam 21625: 8-oxo-dGDP phosphatase NUDT18

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
8-oxo-dGDP phosphatase. [EC: 3.6.1.58]
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.
