Are Ancient Durum Wheats Less Toxic to Celiac Patients? A Study
of α-Gliadin from Graziella Ra and Kamut
Figure 2
Alignment of deduced L and S α-gliadin isoforms of each wheat accession under study. The five epitopes known to be involved in CD, p31–49 (LGQQQPFPPQQPYPQPQPF), DQ2-Glia-α1 [P(F/Y)PQPQLPY], DQ2-Glia-α2 (PQPQLPYPQ), DQ2-Glia-α3 (FRPQQPYPQ), and DQ8-Glia-α1 (QGSFQPSQQN) are shown in red. In light grey: aminoacid substitution; hyphen and light grey: aminoacid deletion. For each α-gliadin isoform the signal peptide is in light blue.
