Fig. (7) Comparison of the N-terminal amino acid sequence of cysteine protease from Actinidia arguta with those of cysteine proteases from Actinidia deliciosa, Actinidia eriantha, Carica papaya and Ananas comsus (fruit and stem).The N-terminal amino acid sequence of cysteine protease from Actinidia arguta is aligned against the sequences of cysteine proteases from Actinidia deliciosa (GenBank accession no. ABQ1090), Actinidia eriantha (ABQ 10191), Carica Papaya (AAB 02650) and Ananas comsus (fruit (BAA 21929) and stem (CAA 08860.1)). Non-conserved amino acid residues among the cysteine proteases of those fruits are shown in filled boxes.
