| GO:0035539 | | 8-oxo-7,8-dihydrodeoxyguanosine triphosphate pyrophosphatase activity | | Catalysis of the reaction: 8-oxo-7,8-dihydrodeoxyguanosine-triphosphate + H2O = 8-oxo-7,8-dihydrodeoxyguanosine phosphate + diphosphate. 8-oxo-7,8-dihydrodeoxyguanosine-triphosphate, or 8-oxo-dGTP, is the oxidised form of the free guanine nucleotide and can act as a potent mutagenic substrate for DNA synthesis causing transversion mutations. 8-oxo-dGTPase hydrolyses 8-oxo-dGTP to its monophosphate form to prevent the misincorporation of 8-oxo-dGTP into cellular DNA. |
| GO:0008413 | | 8-oxo-7,8-dihydroguanosine triphosphate pyrophosphatase activity | | Catalysis of the reaction: 8-oxo-7,8-dihydroguanosine triphosphate = 8-oxo-7,8-dihydroguanosine phosphate + diphosphate. 8-oxo-7,8-dihydroguanosine triphosphate (8-oxo-GTP) is the oxidised form of the free guanine nucleotide and can act as a potent mutagenic substrate for transcription. |
| GO:0044716 | | 8-oxo-GDP phosphatase activity | | Catalysis of the reaction 8-oxo-GDP + H2O = 8-oxo-GMP + phosphate. |
| GO:0044715 | | 8-oxo-dGDP phosphatase activity | | Catalysis of the reaction 8-oxo-dGDP + H2O = 8-oxo-dGMP + phosphate. |
| GO:0047693 | | ATP diphosphatase activity | | Catalysis of the reaction: ATP + H2O = AMP + diphosphate. |
| GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| GO:0000287 | | magnesium ion binding | | Interacting selectively and non-covalently with magnesium (Mg) ions. |
| GO:0030145 | | manganese ion binding | | Interacting selectively and non-covalently with manganese (Mn) ions. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
biological process |
| GO:0006281 | | DNA repair | | The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway. |
| GO:0006260 | | DNA replication | | The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by initiation proteins, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA. |
| GO:0006974 | | cellular response to DNA damage stimulus | | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism. |
