molecular function |
| GO:0008296 | | 3'-5'-exodeoxyribonuclease activity | | Catalysis of the sequential cleavage of mononucleotides from a free 3' terminus of a DNA molecule. |
| GO:0008853 | | exodeoxyribonuclease III activity | | Catalysis of the degradation of double-stranded DNA. It acts progressively in a 3' to 5' direction, releasing 5'-phosphomononucleotides. |
| GO:0004527 | | exonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' or 5' end. |
| 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:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0004518 | | nuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids. |
| GO:0003676 | | nucleic acid binding | | Interacting selectively and non-covalently with any nucleic acid. |
| GO:0042803 | | protein homodimerization activity | | Interacting selectively and non-covalently with an identical protein to form a homodimer. |
biological process |
| GO:0006259 | | DNA metabolic process | | Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides. |
| 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: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. |
| GO:0090305 | | nucleic acid phosphodiester bond hydrolysis | | The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis. |
cellular component |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
