Sodium dodecyl sulphate electrophoresis of wheat gliadins.

چکیده

Polypeptide chain weights of a-, 8and y-gliadin fractions have been estimated by polyacrylamide gel electrophoresis in the presence of mercaptoethanol and sodium dodecyl sulphate. Values lie in the range 32 000 to 44 OOO. When available data on the amino acid analyses were adjusted and compared, significant similarities emerged. It is suggested that these gliadins contain a minimum of 4 cystine residues/molecule. The results provide support for the hypothesis that glutenins and gliadins have evolved from a common precursor. The results of an amino acid analysis of a previously unreported 8-gliadin component are included.

Isolation and characterization of gluten protein types from wheat, rye, barley and oats for use as reference materials

Gluten proteins from wheat, rye, barley and, in rare cases, oats, are responsible for triggering hypersensitivity reactions such as celiac disease, non-celiac gluten sensitivity and wheat allergy. Well-defined reference materials (RM) are essential for clinical studies, diagnostics, elucidation of disease mechanisms and food analyses to ensure the safety of gluten-free foods. Various RM are cur...

Down-Regulating γ-Gliadins in Bread Wheat Leads to Non-Specific Increases in Other Gluten Proteins and Has No Major Effect on Dough Gluten Strength

BACKGROUND Gliadins are a major component of gluten proteins but their role in the mixing of dough is not well understood because their contribution to wheat flour functional properties are not as clear as for the glutenin fraction. METHODOLOGY/PRINCIPAL FINDINGS Transgenic lines of bread wheat with γ-gliadins suppressed by RNAi are reported. The effects on the gluten protein composition and ...
