Multiple amino acid sequence alignment.

<p>sll0067 (Q55139), TeGST (NP_680998), SeGST (YP_171005) and PmGSTB1-1 (P15214) are aligned using ESpript 3.0 software, which utilizes the Clustal W algorithm. Similar residues are shown in yellow boxes; the red boxes represent identical amino acid residues while the amino acid residues with different properties have no boxes. The arrow represents conserved Pro-53. The motif I (49–73) and motif II (130–147) are shown with arrows.
