  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • GO:0009338 An enzyme complex that catalyzes exonucleolytic cleavage (in the presence of ATP) in either 5' to 3' or 3' to 5' direction to yield 5'-phosphooligonucleotides. Exodeoxyribonuclease V shows a preference for double-stranded DNA and possesses DNA-dependent ATPase activity. It acts endonucleolytically on single-stranded circular DNA.
  • GO:0043138 Unwinding a DNA helix in the direction 5' to 3', driven by ATP hydrolysis.
  • GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
  • GO:0016887 Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient.
  • GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
  • GO:0008854 Catalysis of the exonucleolytic cleavage (in the presence of ATP) in either 5' to 3' or 3' to 5' direction to yield 5'-phosphooligonucleotides.
  • GO:0000287 Binding to a magnesium (Mg) ion.
  • GO:0000724 The error-free repair of a double-strand break in DNA in which the broken DNA molecule is repaired using homologous sequences. A strand in the broken DNA searches for a homologous region in an intact chromosome to serve as the template for DNA synthesis. The restoration of two intact DNA molecules results in the exchange, reciprocal or nonreciprocal, of genetic material between the intact DNA molecule and the broken DNA molecule.
  • GO:0000725 A DNA repair process that involves the exchange, reciprocal or nonreciprocal, of genetic material between the broken DNA molecule and a homologous DNA region.
  • GO:0016787 Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc.
  • GO:0003678 Unwinding of a DNA helix, driven by ATP hydrolysis.
  • GO:0006281 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.
