Fig. 6.

Ctenidin 3 ORF gene sequence. The deduced amino acid sequence is presented under the nucleotide sequence. The mature peptide sequence is underlined. The nucleotide sequence of the mature peptide is in bold. The dotted line marks the post-translationally cleaved off lysine and the glycine residue involved in C-terminal amidation of the other glycine. The additional glycines compared to ctenidin 1 and 2 are double underlined. Silent mutations are highlighted in light gray, the mutation causing a Gly-Arg exchange is highlighted in black. Asterisks mark the stop codon
