Nucleotides |
The monomeric units from which DNA or RNA polymers are constructed. They consist of a purine or pyrimidine base, a pentose sugar, and a phosphate group. (From King & Stansfield, A Dictionary of Genetics, 4th ed) |

Oxidation-Reduction |
A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). |

Pyrophosphatases |
A group of enzymes within the class EC 3.6.1.- that catalyze the hydrolysis of diphosphate bonds, chiefly in nucleoside di- and triphosphates. They may liberate either a mono- or diphosphate. EC 3.6.1.-. |

DNA |
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine). |

DNA Damage |
Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS. |

DNA Repair |
The removal of DNA LESIONS and/or restoration of intact DNA strands without BASE PAIR MISMATCHES, intrastrand or interstrand crosslinks, or discontinuities in the DNA sugar-phosphate backbones. |

Nudix Hydrolases |
A group of Mg2+/Mn2+-dependent mainly pyrophosphohydrolases that hydrolyzes structures of NUcleoside DIphosphate linked to another moiety X to nucleoside monophosphate and X-Phosphate. Nudix hydrolases share conserved Nudix box (GX5EX7REUXEEXGU) and degrade variety of substrates including oxidized nucleotides (e.g., MutT) and metabolic intermediates (e.g., THIAMINE PYROPHOSPHATASE). In humans, Nudix superfamily proteins such as MutT proteins participate in DNA damage repairs. Mutations on a nudix hydrolase (NUDT15) are associated with a PURINE-PYRIMIDINE METABOLISM, INBORN ERRORS disorder called THPM2, and mutations in nudix hydrolase (NUDT2) are associated with IDDPN, a developmental intellectual disorder. |
