GIYcGIY-YIG type nucleases (URI domain)
|SMART accession number:||SM00465|
|Interpro abstract (IPR000305):|
During the process of Escherichia coli nucleotide excision repair, DNA damage recognition and processing are achieved by the action of the uvrA, uvrB, and uvrC gene products [(PUBMED:12034838)]. The UvrC proteins contain 4 conserved regions: a domain which interacts with UvrB (Uvr domain), a Helix hairpin Helix (HhH) domain important for 5 prime incision of damage DNA and the homology regions 1 and 2 of unknown function. UvrC homology region 2 is specific for UvrC proteins, whereas UvrC homology region 1 is also shared by few other nucleases.
The homology region 1 is found in the amino terminal region of excinuclease abc subunit c (uvrC), Bacteriophage T4 endonucleases segA, segB, segC, segD and segE; it is also found in putative endonucleases encoded by group I introns of fungi and phage.
