TREE

Phylogenetic tree of selected model organisms from BLASTP results. All proteins putative GTPases of the YlqF/YawG family. Three groupings are observed, a bacterial group, a eukaryotic group and an archaea-eukaryote group. The lack of a bacterial-eukaryotic grouping indicates that no horizontal gene transfer occurred. Furthermore, the distinct bacterial and eukaryotic clades have previously been hypothesises to indicate that the protein was likely a part of the Last Universal Common Ancestor to all extant life forms proteome (Leipe, D. et. al. 2002).
