Similarity plot of the RecA protein family. Similarity values over the first 150 residues of the alignment were calculated using the BLOSUM62 scoring matrix and a window size of 9. A threshold value of 0.8 is indicated by the dashed line. A complete plot using a smaller RecA data set has been previously published .
