Figure 1From: Enhanced ethanol production and reduced glycerol formation in fps1∆ mutants of Saccharomyces cerevisiae engineered for improved redox balancingSchematic diagram of ethanol and glycerol metabolism in S. cerevisiae . Gpd1/Gpd2, glycerol 3-phosphate dehydrogenases; Gpp1/Gpp2, glycerol 3-phosphate phosphatases; Tdh, glyceraldehyde 3-phosphate dehydrogenase; Pgk, phosphoglycerate kinase; Fps1, glycerol exporter (protein channel); TCA, tricarboxylic acid cycle. The strategy used in this work consists of heterologous expression of gapN (encoding NADP+-dependent glyceraldehyde 3-phosphate dehydrogenase) from S. mutans and overexpression of UTR1 (encoding ATP-NADH kinase) from S. cerevisiae.Back to article page
