Bacterial phylogenetic classification was taken from the NCBI Taxonomy database [33]. Column "1997" depicts the number of bacterial RecA homologs used in the multiple sequence alignment from a previous analysis [17]. The adjacent column shows the number of homologs used in the present work. The last column lists a representative species from the corresponding phyla.
