Precursors of neuropeptides in A. rubens that provide novel insights into neuropeptide evolution at the superphylum/phylum level. Predicted signal peptides are shown in blue, putative neuropeptides are shown in red (with cysteine (C) residues underlined), C-terminal glycine (G) residues that are putative substrates for amidation are shown in orange and putative dibasic/tribasic cleavage sites are shown in green.
