Figure 4.

The amino acid sequence of the potato StCcsp (accession no. AY196210) is shown in alignment with the sequences from other species available in GenBank. These include tomato (AF117707.2), Arabidopsis (AF179371.1), soybean (AF329816.1), human (AF002210.1), and yeast Lys7p (AAC49068.1). The amino acids different from the consensus are shaded. Vertical bars separate the three protein domains identified in human and mouse. The asterisks represent the localization of the introns in potato CCS, and the black horizontal line represents the TDFL431. The conserved motifs are in bold lettering, and the consensus sequence is indicated underneath. The circles indicate the Cys residues conserved in human and mouse.
