Fig. 1. Two-dimensional gel electrophoresis (IEF × SDS-PAGE) of glutenin fraction of wheat cultivar Chinese Spring. The HMW-GS, LMW-GS and gliadin fractions are indicated.
Fig. 2. Diagrams representing the structures of typical LMW-GSs as deduced amino acids from their genes. The grey and black stars indicate cysteins involved in inter-molecular and intra-molecular bonds, respectively. Sig; signal peptide, N-ter; N-terminal domain; Rep; repetitive domain and C-ter; C-terminal domain.
Fig. 3. Alignments of deduced amino acid sequences of Glu-A3, Glu-B3 and Glu-D3allelic variants. Identical residues are shaded. The position of cystein residues are marked with filled down arrow. Sig; signal peptide, N-ter; N terminal domain; Rep; repetitive domain and C-ter; C-terminal domain and these positions are marked with filled nabla. GluD3-1 specific hydrophobic residues are underlined. GluA3-1 specific glutamine repeats are also underlined.
