Sequence alignments of the Rad51/RecA-class proteins, and locations of the Xrcc3 amino acid residues mutated in the present study. (A) The amino acid sequence of the human Xrcc3 protein is aligned with the human Rad51B, Rad51C, Rad51D, Rad51 and Dmc1 proteins, and the E.coli RecA protein. (B) Locations of the amino acid residues, Tyr139, Phe180, Phe219, Phe223 and Phe249, of Xrcc3 superimposed on the crystal structure of RecA (56). Red, orange, green, blue and pink spheres indicate the locations of Tyr139, Phe180, Phe219, Phe223 and Phe249, respectively.
