Fig. 1

Nucleotide and deduced amino acid sequences of the PcD6DES gene. Lowercase italics and capital letters indicate 5′/3′-untranslated region and coding sequence, respectively. Bold capital letters represent amino acid residues. The cytochrome b5 domain (the main characteristic of a front-end desaturase) is underlined. Thick underline indicates the heme-binding motif, HPGG. Gray and white boxes indicate the transmembrane domain and histidine box, respectively. Asterisk indicates the translation termination sequence
