FIGURE 1.

Alignment of amino acid sequences of rWTX, nonconventional toxins from Naja species, α-neurotoxins, muscarinic toxins, and water-soluble domain of human Lynx1 (ws-Lynx1). Cysteines are shown over a dark gray background. Position of the rWTX loops is shown by the light gray background. Additional N-terminal methionine residue in the rWTX sequence appearing due to translation of the starting atg codon (underlined) is shown. Sequence similarity between rWTX and other proteins was calculated by EMBOSS Stretcher (EMBL-EBI). Amino acid residue numbering is given for wild-type WTX.
