Figure 2

Possible amino acids in known AKHs as well as in Uniprot sequences, which contain the AKH basic sequence stretches and were obtained with the search term “adipokinetic hormone” (see Materials and Methods). Fixed positions 1 and 8 are shown in bold. Less frequently occurring amino acid residues in known AKHs are marked in grey, possible additional amino acid residues found in predicted sequences are highlighted in green. With this information the mass range (y-axis) of expected peptides was calculated for Pro6- (_P, orange) and non-Pro6 (green) peptides of 8- (8AA) and 10-amino acid (10AA) long sequences.
