Figure 3.

The two amino acid sequences of D. melanogaster desaturases (Tai strain). Sequences show 65.0% identity. The three histidine domains are boxed, and the putative transmembrane domains are indicated by underlines. * shows the amino acid modifications between CS and Tai Desat sequences. Identical and homologous amino acids are indicated with : and ., respectively. desat1 and desat2 cDNA sequences from Tai have been introduced in European Molecular Biology Laboratory (accession nos.: AJ245747 and AJ271415).
