pUC-HUH-EgDes5
The EgDes5 gene encodes a ∆-5 desaturase from Euglena gracilis that catalyzes the conversion of dihomo-γ-linolenic acid (DGLA; C20: 3n-6) to arachidonic acid (ARA; C20:4 n-6).
Characterisation
We constructed a plasmid containing promoter TEF, EgDes5, and terminator Cyc1t through the T4 ligase. The plasmid was linearized by enzyme cleavage and then transformed into engineered Yarrowia lipolytica Po1f-1 and randomly integrated into its genome. EgDes5 gene was expressed under control of promoter TEF, which could catalyze the formation of arachidonic acid (ARA; C20:4 n-6) from eicosadienoic acid (EDA; C20:2n-6). The activity of EgDes5 was examined by gas chromatography.
Result
We integrate one copy of codon-optimized EgDes5 gene from Euglena gracilis under the control of strong promoter PTEF into the genome to obtain the engineered strain Po1f-1 by non-homologous End Joining (NHEJ) The percentage of arachidonic acid (ARA; C20:4 n-6) were 19.4%.
