Phylogenetic analyses suggest that XerL forms a distinct clade from other Xer recombinases. XerL from L. pneumophila was used as a query to search for putative XerL orthologs using blastp and tblastn. The amino acid sequences of recombinases from different Xer groups were aligned with MUSCLE, with one representative per genera included for the XerL-like recombinases. An unrooted phylogeny was generated from the alignment using FastTree. The Xer group designation is denoted with colored labels as indicated. The tree scale bar indicates the number of substitutions per site.
