Comparison of the deduced amino acid sequences of A. leveillei desaturases AL10 and AL21 with related sequences: LaD5 = L. douglasii C₂₀ Δ⁵-desaturase (AF247133); ADS1 = Arabidopsis ADS-like Δ⁹ acyl-lipid desaturase (BAA25180); ADS3 = Arabidopsis palmitoyl-monogalactosyldiacylglycerol Δ⁷-desaturase (FAD5; AY734684); PgD9 = white spruce Δ⁹-desaturase (AF438199); RnSAD = Rattus norvegicus stearoyl-CoA Δ⁹-desaturase (J02585); ScOLE1 = S. cerevisiae Δ⁹ fatty acid desaturase (OLE1; J05676). The conserved His boxes are underlined, as is the C-terminal cytochrome b₅ motif present in OLE1 (dotted line).
