    摘要: Methods of increasing the total lipid content in a eukaryotic cell, the total content of polyunsaturated fatty acids [“PUFAs”], and/or the ratio of desaturated fatty acids to saturated fatty acids by reducing the activity of the heterotrimeric SNF1 protein kinase are disclosed. Preferably, the chromosomal genes encoding the Snf1 α-subunit, Gal83 β-subunit or Snf4 γ-subunit of the SNF1 protein kinase, the upstream regulatory genes encoding Sak1, Hxk2, Glk1 or Reg1, or the downstream genes encoding Rme1, Cbr1 or Snf3 are manipulated in a PUFA-producing strain of the oleaginous yeast Yarrowia lipolytica, resulting in increased total lipid content, as compared to the parent strain comprising the heterotrimeric SNF1 protein kinase not having reduced activity.

    摘要: The present invention relates to a Δ9 desaturase, which has the ability to convert palmitic acid [16:0] or stearic acid [18:0] into palmitoleic acid [16:1] or oleic acid [18:1], respectively. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding Δ9 desaturase along with a method of making long chain polyunsaturated fatty acids (PUFAs) using this Δ9 desaturase in oleaginous yeast is disclosed.

    摘要: Genes have been identified in the Methylomonas genome that are responsive to various metabolic and growth conditions. The identified responsiveness of these genes allows for the use of their promoters in regulated gene expression in C1 metabolizing bacteria. In particular, the hps promoter, which in its native state drives the expression of 3-hexulose-6-phosphate synthase (HPS), was found to be useful for directing expression of heterolgous coding regions (e.g., crtZ) in the obligate methanotroph Methylomonas sp. 16a.
