Total sequenced peptides from the α-AIC3 chain. α-AIC3 whole sequence, showing amino acid residues of the α- and β-subunits; the respective peptides were identified, fragmented and sequenced via MALDI-TOF MS/MS and are highlighted inside the rectangles. In total, six peptides were sequenced, one for the α-subunit and five for the β-subunit. C-terminal end peptides, which were cleaved off to yield the mature subunits, for both subunits are underlined in the figure
