Glycerol-3-phosphate dehydrogenase from Saccharomyces cerevisiae is an enzyme that catalyzes the oxidation of glycerol-3-phosphate (G3P) to dihydroxyacetone phosphate (DHAP), playing a crucial role in glycerol metabolism and energy production. This enzyme acts as the rate-limiting step in glycerol production within Saccharomyces cerevisiae, regulating glycerol formation and accumulation to aid the yeast in adapting to hyperosmotic environments. Additionally, glycerol-3-phosphate dehydrogenase from Saccharomyces cerevisiae is relevant in research within the field of metabolic engineering.
