Figure 3 .
Sequence comparison of x-type HMW-GSs isolated from D and S genomes. The comparison of x-type subunits indicated that the inserted amino acid fragments in 1Dx2.2, 1Dx2.2* and 1Sx subunits (designated as Insertion A, B and C) are independent. Signal peptide is underlined; the N-terminal and C-terminal regions are boxed, respectively. The conserved cysteine residues are indicated by triangles.
