Protein-protein interactions in the ternary FNR-Fd-HDR complex of peppermint GTs. A, Alignment of mature peptide sequences of Fd isoforms present in peppermint GTs. Residues that differ between the major and minor isoform are highlighted in yellow. B, Docking conformation of the FNR-Fd-HDR ternary complex. C, Ribbon diagram of the FNR-Fd interaction. Residues that differ between the major and minor Fd isoforms of GTs are highlighted in red. D, Ribbon diagram of the Fd-HNR interaction. Residues that differ between the major and minor Fd isoforms of GTs are highlighted in red.
