pYLXP-ylPOT1
A composite part consist of pTEF promoter (BBa_K3909008 ), ylPOT1 (BBa_K3909007) and XPR2_terminator (BBa_K3909009).
Our goal is to improve the cell growth of Y. lipolytica and convert a large amount of gutter oil to γ-linolenic acid when Y. lipolytica grows with gutter oil as the sole carbon source . We plan to enhance the oli degradation pathway by expressing three endogenous fatty acid degradation genes ylMEF1 (BBa_K3909006), ylPOT1 (BBa_K3909007), and ylPOXn (from BBa_K3909000 to BBa_K3909005), which are related to the metabolim of transforming acyl-CoA into acetyl-CoA in peroxisome (β-oxidation). Specifically, the β-oxidation includes three steps: i) oxidation, that catalyzed by six acyl-CoA oxidases (translated from ylPOX1 to ylPOX6); ii) hydration and dehydration, that catalyzed by multifunctional enzyme (translated from ylMFE1); and iii) thiolysis, that catalyzed by 3-ketoacyl-CoA thiolase (translated from ylPOT1)[1].
Firstly,we constructed the single gene-overexpressed plasmids by the aforementioned method, including pYLXP’-ylPOT1(BBa_K3909010), pYLXP’-ylMEF1 (BBa_K3909011) and pYLXP’-ylPOXn (from BBa_K3909012 to BBa_K3909017) , which are shown in Figure 1.
