From: A complex and punctate distribution of three eukaryotic genes derived by lateral gene transfer
Bayesian phylogenetic tree of transketolase (TK). The tree was inferred from 473 amino acid characters with branch lengths estimated using PROML. Bootstrap values > 50% are shown. Values shown above a node correspond to PHYML bootstrap support, those below a node correspond to WEIGHBOR support. Eukaryotic sequences are enclosed in boxes where blue corresponds to the major clade of cytosolic proteins, green corresponds to plastid-targeted proteins, and red corresponds to bacterium-derived genes. Filled circles adjacent to taxon names indicate that a complete genome is available from this organism. Multiple isoforms of TK are present in the diatom genomes, both a Chlamydia type TK as well as a eukaryotic form of this enzyme are present. Two types of TK are present in Euglena as well, a form related to the plastid TK of other eukaryotes as well as a Chlamydia type.
