The invention relates to a process for producing one or more polyunsaturated fatty acids by means of heterologous gene expression, the process comprising the steps:
(i) providing a production organism which comprises a gene cluster encoding a polyunsaturated fatty acid biosynthetic pathway, said gene cluster
- being derived from a source organism which differs from the production organism; and
- encompassing a subsequence ER encoding an enoylreductase and a subsequence AT encoding an acyltransferase, wherein the subsequence AT is located downstream with respect to the subsequence ER;
(ii) growing the production organism of step (i) in the presence of a fermentable carbon source whereby one or more polyunsaturated fatty acids are produced; and
(iii) optionally, recovering the one or more polyunsaturated fatty acids.
本发明涉及一种通过异源基因表达生产一种或多种多不饱和脂肪酸的工艺,该工艺包括以下步骤:
(i) 提供一种生产生物体,该生物体包括一个编码多不饱和脂肪酸生物合成途径的基因簇,所述基因簇
- 来源于与生产生物体不同的来源生物体;以及
- 包括编码烯酰还原酶的子序列 ER 和编码酰基转移酶的子序列 AT,其中子序列 AT 位于子序列 ER 的下游;
(ii) 在有可发酵碳源的情况下培养步骤(i)的生产生物体,从而产生一种或多种多不饱和脂肪酸;以及
(iii) 可选地回收一种或多种多不饱和脂肪酸。
