Figure 4

Amino acid sequences of the toxins from the α-KTx₁₅ subfamily. Aa1 [46], AaTX1, and AaTX2 [48] are from Androctonus australis; BmTX3 [47] is from Buthus martensii; AmmTX3 [22] is from Androctonus mauretanicus; AamTX [49] is from Androctonus amoreuxi. Discrepin [54] is from the Venezuelan scorpion Tityus discrepans. Single letter notation is used for amino acid sequences. Z is pyroglutamic acid. *Indicates putative amino acid sequence deduced from cloned cDNA oligonucleotide sequence. The β-sheet consensus sequence is in grey.
