From: The iron-sulfur cluster assembly genes iscS and iscU of Entamoeba histolytica were acquired by horizontal gene transfer

Figure 5

Phylogenetic analysis of E. histolytica IscS and IscU protein sequences using a similar taxonomic sampling. Depicted are unrooted maximum likelihood phylogenetic trees of 29 IscS (left) and 28 IscU (right) protein sequences. The E. histolytica sequences are recovered as part of a well supported monophyletic group comprising the gut bacteria H. pylori and C. jejuni. The orange branches represent those sequences containing the long IscU isoform. Numbers in red represent posterior probabilities as determined by MrBayes [55] where a value of 1.0 represents maximum support (only values above 0.75 are shown). Values in blue represent bootstrap values as determined using PHYML [57], only bootstrap values above 50% are shown.
