Figure 1.
ClustalW alignment of all the cystatin sequences from wheat, rice, barley, sorghum and corn. Few N-terminal and C-terminal amino acid residues are not shown for the clarity of the picture. The conserved signature sequences of the PhyCys are highlighted by enclosing in colored rectangles (Yellow: N-terminal G; Red: LARFAV; Black: QXVXG; Green: P/AW).
