WebMay 2, 2024 · We engineered Yarrowia lipolytica ( Y. lipolytica) at various metabolic levels of lipid biosynthesis, degradation, and regulation for enhanced lipid and citric acid production. We used a one-step double gene knock-in and site-specific gene knock-out strategy. WebOverview of the oxylipin biosynthesis pathway in plants (abbreviations are explained in the text). In the first step the free fatty acid is oxidized by molecular oxygen yielding a hydroperoxy fatty acid. This reaction can either be catalyzed by a lipoxygenase (LOX) or α-dioxygenase (α-DOX). The products of α-DOX decompose nonenzymatically ...
