FadX of Punica granatum

This part is an Yarrowia lipolytica codon optimized version of the bifunctional fatty acid conjugase / desaturase (FadX) from Punica granatum (Uniprot Q84UB8).

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).

Figure 1. Conversion of linoleic acid to punicic acid (both incorporated into phosphatidylcholine) by EC: 1.14.19.16.

The Punica granatum (pomegranate) FadX (Pg-FadX) [1] is a 45.828 kDa protein of 395 amino acids. It's activity leads to the accumulation of important quantities of punicic acid in the pomegranate seeds.

When placed them under the control of a constitutive promoter and expressed in the genome of the oleaginous yeast Yarrowia lipolytica, this part leads to the production of punicic acid, a non natural metabolite of Y. lipolytica. For further details, see the Main Page on the Registry of the Pg-FadX expression plasmid (BBa_K2983181) that is able to integrate, upon transformation, into the genome of a Y. lipolytica Po1d stain.

-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).
