Yeast host cells and methods for producing fatty alcohols

The present invention provides for a genetically modified yeast cell comprising at least six or more of the following modifications: increased expression of Mus musculus fatty acid reductase, acetyl-CoA carboxylase, fatty acid synthase 1, fatty acid synthase 2, a mutant of the bottleneck enzyme encoded by ACC1 insensitive to post-transcriptional and post-translational repression, and/or a desaturase encoded by OLE1, and reduced expression of DGA1, HFD1, ADH6, and/or GDH1. The present invention provides a method for constructing the genetically modified yeast cell, and a method for producing a fatty alcohol from the genetically modified yeast cell.

Plant unusual fatty acids: learning from the less common

The plant kingdom contains an abundance of structurally diverse fatty acids referred to as unusual fatty acids. Unusual fatty acids on plant surfaces can form polyesters that contribute to the function of cutin as a barrier for water loss and pathogen protection. Unusual fatty acids are also found as abundant components of seed oils of selected species and often confer desirable properties for industrial and nutritional applications. Here in this paper, we review recent findings on the biosynthesis and metabolism of unusual fatty acids in cutin and seed oils and use of this information for enzyme structure-function studies and seed oil metabolic engineering. We also highlight the recent discovery of unusual fatty acids that are formed from a previously undescribed variation of fatty acid elongation.
