FunFam 247279: DNA replication helicase

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 8 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

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.
1 P38859 (/IDA)
5'-3' DNA helicase activity GO:0043139
Catalysis of the unwinding of the DNA helix in the direction 5' to 3'.
1 P38859 (/IDA)
Single-stranded DNA-dependent ATPase activity GO:0043142
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction requires the presence of single-stranded DNA, and it drives another reaction.
1 P38859 (/IDA)
4 iron, 4 sulfur cluster binding GO:0051539
Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
1 P38859 (/IDA)

There are 12 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Meiotic DNA double-strand break processing GO:0000706
The cell cycle process in which the 5' to 3' exonucleolytic resection of the DNA at the site of the break to form a 3' single-strand DNA overhang occurs. This takes place during meiosis.
1 P38859 (/IGI)
Telomere maintenance GO:0000723
Any process that contributes to the maintenance of proper telomeric length and structure by affecting and monitoring the activity of telomeric proteins, the length of telomeric DNA and the replication and repair of the DNA. These processes includes those that shorten, lengthen, replicate and repair the telomeric DNA sequences.
1 P38859 (/IMP)
DNA double-strand break processing GO:0000729
The 5' to 3' exonucleolytic resection of the DNA at the site of the break to form a 3' single-strand DNA overhang.
1 P38859 (/IGI)
DNA double-strand break processing GO:0000729
The 5' to 3' exonucleolytic resection of the DNA at the site of the break to form a 3' single-strand DNA overhang.
1 P38859 (/IMP)
DNA strand renaturation GO:0000733
The identification and annealing of complementary base pairs in single-strand DNA.
1 P38859 (/IDA)
Replicative cell aging GO:0001302
The process associated with progression of the cell from its inception to the end of its lifespan that occurs as the cell continues cycles of growth and division.
1 P38859 (/IMP)
DNA-dependent DNA replication GO:0006261
A DNA replication process that uses parental DNA as a template for the DNA-dependent DNA polymerases that synthesize the new strands.
1 P38859 (/IDA)
DNA-dependent DNA replication GO:0006261
A DNA replication process that uses parental DNA as a template for the DNA-dependent DNA polymerases that synthesize the new strands.
1 P38859 (/IMP)
Lagging strand elongation GO:0006273
The synthesis of DNA from a template strand in a net 3' to 5' direction. Lagging strand DNA elongation proceeds by discontinuous synthesis of short stretches of DNA, known as Okazaki fragments, from RNA primers; these fragments are then joined by DNA ligase. Although each segment of nascent DNA is synthesized in the 5' to 3' direction, the overall direction of lagging strand synthesis is 3' to 5', mirroring the progress of the replication fork.
1 P38859 (/IMP)
DNA repair 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.
1 P38859 (/IMP)
Cellular response to DNA damage stimulus GO:0006974
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.
1 P38859 (/IDA)
Small molecule metabolic process GO:0044281
The chemical reactions and pathways involving small molecules, any low molecular weight, monomeric, non-encoded molecule.
1 P38859 (/TAS)

GO Term Annotations Evidence
Nuclear chromosome, telomeric region GO:0000784
The terminal region of a linear nuclear chromosome that includes the telomeric DNA repeats and associated proteins.
1 P38859 (/IDA)
Nucleus GO:0005634
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.
1 P38859 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 P38859 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 P38859 (/TAS)
Site of double-strand break GO:0035861
A region of a chromosome at which a DNA double-strand break has occurred. DNA damage signaling and repair proteins accumulate at the lesion to respond to the damage and repair the DNA to form a continuous DNA helix.
