Fig. 1From: Enhanced production of amyrin in Yarrowia lipolytica using a combinatorial protein and metabolic engineering approachBiosynthesis of α- and β-amyrins in the engineered Y. lipolytica. Extracellular carbon sources were assimilated and converted into α- and β amyrins via the mevalonate (MVA) pathway. Metabolites are identified in black. Endogenous and foreign genes that were up-regulated are listed in red and green, respectively. HMG1: hydroxymethylglutaryl-CoA reductase; ERG20: farnesyl diphosphate synthase; ERG9: squalene synthase; ERG1: squalene monooxygenase; CrMAS: C. roseus multifunctional amyrin synthaseBack to article page
