Figure 5: Phylogenetic analysis of GlxI family.

Reconstructed phylogenetic tree obtained from domain sequences of 81 putative GlxI sequences showed two major clusters, representing Zn- and Ni-GlxI domains. The Zn-GlxI from C. pelagibacter and Sphingomonas that have been acquired by horizontal gene transfer events in ancestors of eukaryotes and plants respectively have been marked by asterisk. Bootstrap values above 50% for 1000 bootstrap is depicted on the branches.
