Abstract

The metabolism of arachidonic acid (ARA) by cytochrome P450 ω/ω-1-hydroxylases leads to the formation of 20- hydroxyeicosatetraenoic acid (20-HETE), which is an important lipid-signaling molecule involved in regulation of vascular tone, angiogenesis, and inflammation. Development of a simple method to prepare 20-HETE would greatly facilitate the investigation of its biological activities. The nonpathogenic yeast Starmerella bombicola has been shown to convert exogenously added arachidonic acid to 20-HETE via the biosynthetic pathway of sophorolipids; however, the yield was low. Here we demonstrate that genetic knockout of multifunctional enzyme type 2 (MFE-2), which is involved in the β-oxidation of fatty acids, significantly increases the yield of ARA conversion to 20-HETE and allows practical preparation of 20-HETE.
