CC -!- FUNCTION: The UvrABC repair system catalyzes the recognition and CC processing of DNA lesions. A damage recognition complex composed of 2 CC UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon binding of CC the UvrA(2)B(2) complex to a putative damaged site, the DNA wraps CC around one UvrB monomer. DNA wrap is dependent on ATP binding by UvrB CC and probably causes local melting of the DNA helix, facilitating CC insertion of UvrB beta-hairpin between the DNA strands. Then UvrB CC probes one DNA strand for the presence of a lesion. If a lesion is CC found the UvrA subunits dissociate and the UvrB-DNA preincision complex CC is formed. This complex is subsequently bound by UvrC and the second CC UvrB is released. If no lesion is found, the DNA wraps around the other CC UvrB subunit that will check the other stand for damage. CC {ECO:0000256|ARBA:ARBA00025647, ECO:0000256|HAMAP-Rule:MF_00204}. CC -!- SUBUNIT: Forms a heterotetramer with UvrA during the search for CC lesions. Interacts with UvrC in an incision complex. CC {ECO:0000256|ARBA:ARBA00026033, ECO:0000256|HAMAP-Rule:MF_00204, CC ECO:0000256|RuleBase:RU003587}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496, CC ECO:0000256|HAMAP-Rule:MF_00204, ECO:0000256|RuleBase:RU003587}. CC -!- DOMAIN: The beta-hairpin motif is involved in DNA binding. CC {ECO:0000256|HAMAP-Rule:MF_00204}. CC -!- SIMILARITY: Belongs to the UvrB family. {ECO:0000256|ARBA:ARBA00008533, CC ECO:0000256|HAMAP-Rule:MF_00204, ECO:0000256|RuleBase:RU003587}.
