Multi-alignment of the deduced amino acid sequence of TbPT0, TbPT1, TbPT2, TbPT3, TbPT4, and TbPT5. Alignment was performed using CLUSTALW software (MacVector, Intelligenetics). Labeled solid lines over the TbPT0 sequence indicate the predicted TM by TMHMM software. Identities are showed by the black background and similarities by gray background. The double line under the TbPT5 sequence indicates the MYDAEA sequence signature. The numbers at the left and right indicate amino acid positions.
