Sequence alignment of peptide toxins in the NaSpTx family 1. (A) Alignment of mature toxin sequences in NaSpTx family 1. Cysteines are highlighted in red; (B) Sequence logo for alignment in NaSpTx family 1. Residues shown in black are hydrophobic, those shown in red are negatively charged, those shown in blue are positively charged, and those shown in green are polar uncharged. The overall height of the stack indicates the sequence conservation at that position, while the height of letter within the stack indicates the relative frequency of each amino acid.
