UvrA DNA-binding domain
UvrA interaction domain
This domain found in UvrA proteins interacts with the UvrB protein. (from Pfam)
ATP-binding cassette domain-containing protein
ABC transporters for a large family of proteins responsible for translocation of a variety of compounds across biological membranes. ABC transporters are the largest family of proteins in many completely sequenced bacteria. ABC transporters are composed of two copies of this domain and two copies of a transmembrane domain Pfam:PF00664. These four domains may belong to a single polypeptide as in Swiss:P13569, or belong in different polypeptide chains. [1]. 1864505.

excinuclease ABC subunit UvrA
The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 uvrA and 2 uvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by uvrB, the uvrA molecules dissociate
excinuclease ABC subunit UvrA is a DNA-binding ATPase that recognizes DNA adducts in the nucleotide excision repair process catalyzed by the UvrABC excinuclease repair system
This family is a member of the ABC transporter superfamily of proteins of which all members for which functions are known except the UvrA proteins are involved in the transport of material through membranes. UvrA orthologs are involved in the recognition of DNA damage as a step in nucleotide excision repair. This family is based on the phylogenomic analysis of JA Eisen (1999, Ph.D. Thesis, Stanford University).
