Pathway Edits
- ScSDH1 succinate dehydrogenase subunit 1 partial knockdown (50%) to reduce succinate oxidation to fumarate, accumulating succinic acid in yeast
- ScSDH2 iron-sulfur subunit 2 activity reduction via weak promoter replacement for SDH complex downregulation
- ScFUM1 fumarase overexpression for futile cycling of fumarate-to-malate, indirectly elevating succinate by reducing fumarate pool pressure
- ScMDH2 malate dehydrogenase cytosolic isoform overexpression for enhanced OAA-to-malate cycling supporting succinate accumulation
- ScICL1 isocitrate lyase overexpression for glyoxylate cycle succinate generation as complementary route to TCA-derived succinate
- ScMLS1 malate synthase upregulation for glyoxylate-to-malate step, allowing net succinate export from glyoxylate shunt
