|
DNA binding
|
Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
GO:0003676
|
nucleic acid binding
|
Interacting selectively and non-covalently with any nucleic acid. |
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:0000166
|
nucleotide binding
|
Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
GO:0003887
|
DNA-directed DNA polymerase activity
|
Catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1); the synthesis of DNA from deoxyribonucleotide triphosphates in the presence of a DNA template and a 3'hydroxyl group. |
GO:0008408
|
3'-5' exonuclease activity
|
Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' end. |
GO:0016035
|
zeta DNA polymerase complex
|
A heterodimeric DNA polymerase complex that catalyzes error-prone DNA synthesis in contexts such as translesion synthesis and double-stranded break repair. First characterized in Saccharomyces, in which the subunits are Rev3p and Rev7p; a third protein, Rev1p, is often associated with the polymerase dimer. |
GO:0019985
|
translesion synthesis
|
The replication of damaged DNA by synthesis across a lesion in the template strand; a specialized DNA polymerase or replication complex inserts a defined nucleotide across from the lesion which allows DNA synthesis to continue beyond the lesion. This process can be mutagenic depending on the damaged nucleotide and the inserted nucleotide. |
