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:0000255|HAMAP-
CC       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:0000255|HAMAP-Rule:MF_00204}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00204}.
CC   -!- DOMAIN: The beta-hairpin motif is involved in DNA binding.
CC       {ECO:0000255|HAMAP-Rule:MF_00204}.
CC   -!- SIMILARITY: Belongs to the UvrB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00204}.
