| molecular function |
|---|
| | GO:0008409 | | 5'-3' exonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 5' end. |
| | GO:0017108 | | 5'-flap endonuclease activity | | Catalysis of the cleavage of a 5' flap structure in DNA, but not other DNA structures; processes the 5' ends of Okazaki fragments in lagging strand DNA synthesis. |
| | GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| | GO:0003824 | | catalytic activity | | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
| | GO:0004519 | | endonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks. |
| | 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:0016788 | | hydrolase activity, acting on ester bonds | | Catalysis of the hydrolysis of any ester bond. |
| | 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. |
| 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:0043137 | | DNA replication, removal of RNA primer | | Removal of the Okazaki RNA primer from the lagging strand of replicating DNA, by a combination of the actions of DNA polymerase, DNA helicase and an endonuclease. |
| | 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. |
