Figure 18.

Precursors of cysteine-rich peptide hormones and growth factors in A. rubens. Predicted signal peptides are shown in blue, putative peptide hormones/growth-factors 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 cleavage sites are shown in green. For ArIGFP1 and ArIGFP2, the C-peptide is shown in black, the D-domain (for ArIGFP1) is shown in olive and the E-domain is shown in maroon.
