Probably not involved in DNA repair; Belongs to the SNF2/RAD54 helicase family. RapA subfamily. (968 aa)

STY0529Conserved hypothetical protein; Binds to DNA and alters its conformation. May be involved in regulation of gene expression, nucleoid organization and DNA protection. (109 aa)
STY0530Recombination protein RecR; May play a role in DNA repair. It seems to be involved in an RecBC-independent recombinational process of DNA repair. It may act with RecF and RecO. (201 aa)
STY0831Excision nuclease ABC subunit B; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon binding of the UvrA(2)B(2) complex to a putative damaged site, the DNA wraps around one UvrB monomer. DNA wrap is dependent on ATP binding by UvrB and probably causes local melting of the DNA helix, facilitating insertion of UvrB beta-hairpin between the DNA strands. Then UvrB probes one DNA strand for the presence of a lesion. If a lesion is found the UvrA subunits dissoc [...] (673 aa)
