Functional Family Nucleotide triphosphate diphosphatase NUDT15

Enzyme Information

3.6.1.55
8-oxo-dGTP diphosphatase.
based on mapping to UniProt Q9CA40
8-oxo-dGTP + H(2)O = 8-oxo-dGMP + diphosphate.
-!- 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).
3.6.1.67
Dihydroneopterin triphosphate diphosphatase.
based on mapping to UniProt Q9CA40
7,8-dihydroneopterin 3'-triphosphate + H(2)O = 7,8-dihydroneopterin 3'-phosphate + diphosphate.
-!- The enzyme participates in a folate biosynthesis pathway, which is found in bacteria, fungi, and plants. -!- Formerly EC 3.6.1.n4.
3.6.1.22
NAD(+) diphosphatase.
based on mapping to UniProt Q9CA40
NAD(H) + H(2)O = AMP + NMN(H).
-!- This enzyme, described from plants, animals, and bacteria, can act on both reduced and oxidized forms of its substrate, although enzymes from different organisms have different preferences. -!- Also acts on other dinucleotides, including NADP(H), FAD(H(2)), and the thionicotinamide analogs of NAD(+) and NADP(+).
