3.6.1.56 | 2-hydroxy-ATP + H2O |
8-oxo-dGTP i.e. 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate. MTH1 hydrolyzes oxidized purine nucleoside triphosphates such as 8-oxo-dGTP, 8-oxo-dATP, 2-hydroxy-dATP, and 2-hydroxy-ATP to monophosphates, and thus avoids errors caused by their misincorporation during DNA replication or transcription, which may result in carcinogenesis or neurodegeneration |
3.6.1.56 | 2-hydroxy-dATP + 2 H2O |
8-oxo-dGTP i.e. 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate. MTH1 protein is an antimutagenic (2'-deoxy) ribonucleoside 5'-triphosphate pyrophosphohydrolase that prevents the incorporation of oxidatively modified nucleotides into nucleic acids. It decomposes most specifically the miscoding products of oxidative damage to purine nucleic acid precursors (e.g. 8-oxo-dGTP, 2-hydroxy-dATP, 2-hydroxy-ATP, 8-oxo-GTP) that may cause point mutations or transcription errors when incorporated into DNA and RNA, respectively |

3.6.1.56 | 2-hydroxy-dATP + H2O |
8-oxo-dGTP i.e. 8-oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate. MTH1 hydrolyzes oxidized purine nucleoside triphosphates such as 8-oxo-dGTP, 8-oxo-dATP, 2-hydroxy-dATP, and 2-hydroxy-ATP to monophosphates, and thus avoids errors caused by their misincorporation during DNA replication or transcription, which may result in carcinogenesis or neurodegeneration |
3.6.1.56 | 2-hydroxy-dATP + H2O |
human MTH1 hydrolyzes oxidized purine nucleoside triphosphates, such as 8-oxo-dGTP and 2-oxo-dATP, to monophosphates, thereby preventing the misincorporation of these oxidized nucleotides during replication |
3.6.1.56 | 2-hydroxy-dATP + H2O |
MTH1 protects cells from H2O2-induced cell dysfunction and death by hydrolyzing oxidized purine nucleotides including 8-oxo-dGTP and 2-OH-dATP. These alterations may be partly attributed to a mitochondrial dysfunction |
