molecular function |
| GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| GO:1990238 | | double-stranded DNA endodeoxyribonuclease activity | | Catalysis of the hydrolysis of ester linkages within a double-stranded deoxyribonucleic acid molecule by creating internal breaks. |
| 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:0016874 | | ligase activity | | Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
| 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:0004803 | | transposase activity | | Catalysis of the transposition of transposable elements or transposons. Transposases are involved in recombination required for transposition and are site-specific for the transposon/transposable element. |
biological process |
| GO:0015074 | | DNA integration | | The process in which a segment of DNA is incorporated into another, usually larger, DNA molecule such as a chromosome. |
| GO:0006310 | | DNA recombination | | Any process in which a new genotype is formed by reassortment of genes resulting in gene combinations different from those that were present in the parents. In eukaryotes genetic recombination can occur by chromosome assortment, intrachromosomal recombination, or nonreciprocal interchromosomal recombination. Intrachromosomal recombination occurs by crossing over. In bacteria it may occur by genetic transformation, conjugation, transduction, or F-duction. |
| 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:0090305 | | nucleic acid phosphodiester bond hydrolysis | | The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis. |
| GO:0032196 | | transposition | | Any process involved in mediating the movement of discrete segments of DNA between nonhomologous sites. |
| GO:0006313 | | transposition, DNA-mediated | | Any process involved in a type of transpositional recombination which occurs via a DNA intermediate. |
| GO:0039693 | | viral DNA genome replication | | The replication of a viral DNA genome. |
cellular component |
| GO:0018995 | | host | | Any organism in which another organism, especially a parasite or symbiont, spends part or all of its life cycle and from which it obtains nourishment and/or protection. |
| GO:0030430 | | host cell cytoplasm | | The cytoplasm of a host cell. |
