CC -!- FUNCTION: The UvrABC repair system catalyzes the recognition and CC processing of DNA lesions. A damage recognition complex composed CC of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon CC binding of the UvrA(2)B(2) complex to a putative damaged site, the CC DNA wraps around one UvrB monomer. DNA wrap is dependent on ATP CC binding by UvrB and probably causes local melting of the DNA CC helix, facilitating insertion of UvrB beta-hairpin between the DNA CC strands. Then UvrB probes one DNA strand for the presence of a CC lesion. If a lesion is found the UvrA subunits dissociate and the CC UvrB-DNA preincision complex is formed. This complex is CC subsequently bound by UvrC and the second UvrB is released. If no CC lesion is found, the DNA wraps around the other UvrB subunit that CC will check the other stand for damage. {ECO:0000256|HAMAP- CC Rule:MF_00204, ECO:0000256|SAAS:SAAS00893482}. CC -!- SUBUNIT: Forms a heterotetramer with UvrA during the search for CC lesions. Interacts with UvrC in an incision complex. CC {ECO:0000256|HAMAP-Rule:MF_00204, ECO:0000256|SAAS:SAAS00893536}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00204, CC ECO:0000256|SAAS:SAAS00893513}. 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|HAMAP- CC Rule:MF_00204, ECO:0000256|SAAS:SAAS00893535}.
