The present invention relates to Δ8 desaturase genes, which have the ability to convert eicosadienoic acid (EDA; 20:2 ω-6) to dihomo-γ-linolenic acid (DGLA; 20:3 ω-6) and/or eicosatrienoic acid (ETrA; 20:3 ω-3) to eicosatetraenoic acid (ETA; (20:3 ω-3). Isolated nucleic acid fragments and recombinant DNA constructs comprising such fragments encoding Δ8 desaturases along with a method of making long-chain polyunsaturated fatty acids (PUFAs) using these Δ8 desaturases in oleaginous yeast are disclosed.

摘要:
Described are methods of reducing the amount of byproduct organic acids during fermentation of an organism, based on expression of a heterologous malonyl-CoA synthetase. A polyunsaturated fatty acid [“PUFA”]-producing strain of the oleaginous yeast Yarrowia lipolytica was engineered to express a heterologous malonyl-CoA synthetase gene. The expression did not effect the production of PUFAs, but did result in a reduced amount of malonates when compared to the amount of malonates produced in the parental strain not expressing malonyl-CoA synthetase.

The present invention relates to mutant Δ8 desaturase genes, which have the ability to convert eicosadienoic acid [20:2 ω-6, EDA] to dihomo-γ-linolenic acid [20:3, DGLA] and/or eicosatrienoic acid [20:3 ω-3, ETrA] to eicosatetraenoic acid [20:3 ω-3, ETA]. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ8 desaturase along with methods of making long-chain polyunsaturated fatty acids (PUFAs) using these mutant Δ8 desaturases in plants and oleaginous yeast are disclosed.
摘要:
The present invention relates to a Δ5 desaturase, which has the ability to convert dihomo-γ-linolenic acid (DGLA; 20:3 ω-6) to arachidonic acid (ARA; 20:4 ω-6) and/or eicosatetraenoic acid (ETA; 20:4 ω-3) to eicosapentaenoic acid (EPA; 20:5 ω-3). Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ5 desaturase along with a method of making long chain polyunsaturated fatty acids (PUFAs) using this Δ5 desaturase in oleaginous yeast are disclosed.
摘要:
The present invention relates to Δ17 desaturases, which have the ability to convert ω-6 fatty acids into their ω-3 counterparts (i.e., conversion of arachidonic acid [20:4, ARA] to eicosapentaenoic acid [20:5, EPA]). Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ17 desaturases along with a method of making long-chain polyunsaturated fatty acids (PUFAs) using these Δ17 desaturases in oleaginous yeast are disclosed.
