Alignment of full-length gamma gliadins deduced from consensus sequences of Butte 86 contigs. Alignments were performed with ClustalW2 using a blosum matrix and default settings. Identical residues are indicated by asterisks, conserved substitutions by colons and semi-conserved substitutions by periods. The eight conserved cysteine residues are enclosed in boxes. The position of the extra cysteine residue in #3, 4, 8 and 10 is indicated with an arrow.
