What's Happening?
Researchers have developed a strategy to improve chemical production in Issatchenkia orientalis by decompartmentalizing yeast mitochondrial metabolism. This involves expressing a pyruvate dehydrogenase (PDH) complex in the cytosol to generate more cytosolic NADH, enhancing succinic acid (SA) production. The study explores the coupling of the reductive tricarboxylic acid (rTCA) pathway with a glyoxylate shunt to optimize carbon flux and improve SA yield. The approach aims to increase the supply of cytosolic NADH and redirect acetyl-CoA to SA synthesis, offering potential for enhanced production of bio-based chemicals.
