Phylogeny of sortase homologs. Clustal X [58] was used to align the protein sequences of sortase homologs of Gram-positive bacteria. The phylogenetic tree of the housekeeping sortases (green) was reconstructed with the neighbor-joining algorithm [59] using the program PAUP 4.0 10β. Numbers on the branches specify bootstrap values. Different classes of sortase are color-coded; the number of sortases in each class is indicated by dots.
