Figure 2. Predicted amino acid sequences of the toxin coding region of alleles of conotoxin locus E1 of Conus ebraeus.

Amino acids are provided as single letter codes; dots are used to indicate identity to the amino acid of the first sequence given. To illustrate radical amino acid substitutions, amino acids with similar chemical properties are provided in similar background colors (coloring based on the ‘amino’ scheme utilized in Jmol, a Java viewer for chemical structures (http://www.jmol.org/)). Amino acid sequences of E1b_i and E1b_ii were combined because they exhibit no nonsynonymous substitutions with the toxin coding region.
