Succinic acid and mannitol biosynthesis pathway from glucose as the sole carbon source in Yarrowia lipolytica. The engineered route for overexpression of genes in this study is highlighted with green arrows, deleted pathways highlighted in red, and downregulated pathway in orange. Gene nomenclature: Acetyl-CoA hydrolase (ACH1), phosphoenolpyruvate carboxykinase from A. succinogenes (AsPCK), pyruvate carboxylase from A. succinogenes (AsPYC), Isocitrate lyase (ICL), α-ketoglutarate dehydrogenase (KGDH), malate dehydrogenase (MDH), malate synthase (MLS), pyruvate carboxylase from S. cerevisiae (ScPYC), phosphoenolpyruvate carboxykinase from S. cerevisiae (ScPCK), succinyl-CoA synthase beta-subunit (SCS2), dicarboxylic acid transporter from S. pombe (SpMae1), pyruvate carboxylase from Y.lipolytica (YlPYC), phosphoenolpyruvate carboxykinase (YlPCK), succinate dehydrogenase subunit 1 under the control of truncated promoter (tPSDH1).
