The sunflower plastidial ω3-fatty acid desaturase (HaFAD7) contains the signalling determinants required for targeting to, and retention in, the endoplasmic reticulum membrane in yeast but requires co-expressed ferredoxin for activity

Metabolic engineering is focus in the production of a huge diversity of polyunsaturated fatty acids with an economical interest. In this study, we characterized factors contributing to improve the activity of sunflower plastidial ω3-desaturase, HaFAD7, expressed in yeast.
