Schematic overview of the structure of gamma-gliadins. The proteins consist of a short N-terminal signal peptide (S) followed by a unique N-terminal domain (I) and a repetitive domain (II). Domain III contains most (often 6) of the cysteines. IV is rich in glutamine. Two conserved cysteines are in V. Eight cysteine residues (indicated with vertical lines) can form four interchain disulfide bonds (indicated as connections between lines). Figure after [9].
