From: Evolution of mal ABC transporter operons in the Thermococcales and Thermotogales
Relationships among families of apparent maltose ABC transporter operons in archaea and bacteria. Homologs of the P. furiosus MdxE (PF1938) 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.
