Fig. 3.

Sequence aligment of the C-terminal parts of soybean and Arabidopsis ferritin subunits. Identical and similar residues between at least three proteins are boxed in black and grey, respectively. Amino acids are numbered from the translational start methionine. The arginine in position 234 of Soy H-1 subunit was shown to be the last residue of the processed 26·5-kDa form (Masuda et al., 2001). This residue and the corresponding arginines in Arabidopsis subunits are indicated in red.
