Conjugated linolenic acids (CLnAs) are synthetized by bifunctional fatty acid conjugase / desaturase (FadX) enzymes from linoleic acid, C18:2 (9Z,12Z).Thus, to convert it into punicic acid, only the presence of a EC: 1.14.19.16 enzyme is necessary (Figure 1).

FadX of Trichosanthes kirilowii

This part is an Yarrowia lipolytica codon optimized version of the bifunctional fatty acid conjugase / desaturase (FadX) from Trichosanthes kirilowii (Uniprot Q84UC0).

Usage and Biology

The bifunctional fatty acid conjugase / desaturase FadX (EC: 1.14.19.16) catalyses the conversion of linoleic acid, C18:2 (9Z,12Z) into punicic acid, C18:3 (9Z, 11E, 13Z) (Figure 1).

The Trichosanthes kirilowii (chinese cucumber / chinese snake gourd) FadX (Tk-FadX) [1] is a 44.918 kDa protein of 387 amino acids. It's activity leads to the accumulation of important quantities of punicic acid in the seeds.
