EhElo9 encodes ∆-9 elongase from Emiliania huxleyi which functions in the Δ-9 elongase/desaturase pathway and could convert C18:2 to C20:2.

Characterisation

We integrated EhElo9 controlled by the YAT promoter to the SCP2 site of the genome of Y. lipolytica through this segment. Then we detected the proportion of C18:2 and C20:2 by gas chromatography (GC) and test the activity of ∆-9 elongase according to the results. And the EhElo9 controlled by the TEF promoter (BBa_K4343081) was used as the control group.

Result

it was found that there was no significant change in EPA yield under the YAT promoter (Fig. ), which demonstrates that the promoter optimization did not have a significant effect on EPA yield.(Fig: YAT)
