Sequence comparison of Buckwheat DFR proteins with those of other plants. a Alignment of the deduced amino acid sequences of FeDFR, FeDFR1a and FeDFR2 using version 2.1 of the ClustalW software and Boxshade. Identical residues are highlighted in black and similar residues are highlighted in gray. Amino acid sequences corresponding to the regions that determine substrate specificity are boxed. Numbers indicate the positions of the amino acid residues in each sequence. b Alignment of the regions that determine DFR substrate specificity of buckwheat and other plants. The amino acid position corresponding to asparagine 134 of the Gerbera DFR is highlighted in light blue. The extra glycine residue in FeDFR2 is highlighted in red. The arrowhead indicates the other residue that contribute to the activity [7]
