Comments
Comments UvrA, UvrB, and UvrC form complexes that recognize DNA damage, and incise DNA 3' and 5' to damaged lesions in nucleotide excision repair. UvrA-C function according to the scheme below [PUB_0461]: UvrA2B complex recognizes DNA damage UvrA hydrolyzes ATP and dissociates from UvrB, leaving a DNA-UvrB complex UvrC complexes with UvrB, inducing a conformational change in UvrB which nicks the DNA 4 nt 3' to the damage UvrC nicks the DNA 7 nt 5' to the damage DNA-binding Distances between 3' and 5' cleavages is 12 bp [PUB_0461]. UvrAB footprint is 10 nt [PUB_0713], 18 nt [PUB_0709], 19 nt [PUB_0710], 20 nt [PUB_0712]. UvrA2 and UvrB have footprints of 33 nt and 24 nt [PUB_0515]. Composition [PUB_0006].
