Figure 2From: Polyploid genome of Camelina sativarevealed by isolation of fatty acid synthesis genesFAD2 and FAE1 protein alignment. (A) Amino acid sequence comparison of the three Camelina sativa FAD2 sequences, Arabidopsis thaliana FAD2 sequence [Genbank: NP_187819], Brassica rapa FAD2 sequence [Genbank: AJ459107], Glycine max FAD2-3 sequence [Genbank: DQ532371], Zea mays FAD2 sequence [Genbank: AB257309]. Blue underlines below the sequences indicate amino acids conserved in all 50 FAD2 sequences compared by Belo et al.[46] while the green underline indicates the ER localization signal [45]. The three His boxes described by Tocher et al [44] are indicated with red boxes. (B) Amino acid sequence comparison of the three Camelina sativa FAE1 sequences, Arabidopsis thaliana FAE1 [Genbank:NP_195178], Crambe abyssinica [Genbank: AAX22298], Brassica rapa Heac FAE1 [Genbank: Y14975], Brassica rapa Leac FAE1 [Genbank: Y14974], Limnanthes alba (meadow foam) [Genbank: AF247134] and Tropaeolum majus (nasturtium) [Genbank: ABD77097]. Blue underlines below the sequence indicate the asparagine at position 424 and the highly conserved histidine and cysteine residues described by Ghanevati and Jaworski [49, 50]. The red box indicates the region highly conserved among condensing enzymes in very long chain fatty acid biosynthesis [62] Abbreviations: Heac = High erucic acid, Leac = Low erucic acid.Back to article page
