Abstract

Fatty acids or their activated forms, fatty acyl-CoAs and fatty acyl-ACPs, are important precursors to synthesize a wide variety of fuels and chemicals, including but not limited to free fatty acids (FFAs), fatty alcohols (FALs), fatty acid ethyl esters (FAEEs), and alkanes. However, Saccharomyces cerevisiae, an important cell factory, does not naturally accumulate fatty acids in large quantities. Therefore, metabolic engineering strategies were carried out to increase the glycolytic fluxes to fatty acid biosynthesis in yeast, specifically to enhance the supply of precursors, eliminate competing pathways, and bypass the host regulatory network. This review will focus on the genetic manipulation of both structural and regulatory genes in each step for fatty acids overproduction in S. cerevisiae, including from sugar to acetyl-CoA, from acetyl-CoA to malonyl-CoA, and from malonyl-CoA to fatty acyl-CoAs. The downstream pathways for the conversion of fatty acyl-CoAs to the desired products will also be discussed.
