Relationship among apparent maltose ABC transporters related to the Mal3 homologs found in some members of the Thermotogales. Homologs of the Tc. litoralis MalE were gathered using that sequence as query in BLASTP. Concatenated sequences of these SBP homologs and their cognate MSP and ABP from each operon were prepared, aligned and analyzed. A ML tree generated in PHYML is shown. Values shown are Bayesian posterior probabilities followed by bootstrap support values calculated with PHYML. Bootstrap support values below 800 and posterior probabilities below 0.8 are not shown. For reference, the gi numbers of the MalE (SBP) sequence for each operon are provided. Archaeal sequences are shown in red, those from Thermotogales in blue, and from other bacteria in black. The tree depicted here should be considered unrooted.
