The GABA shunt pathway involves three enzymes: glutamate decarboxylase (GAD), GABA aminotransferase (GAT), and succinate semialdehyde dehydrogenase (SSADH). These enzymes act in concert to convert glutamate (α-ketoglutarate) to succinate. Deletion mutations in each of these genes in Saccharomyces cerevisiae resulted in growth defects at 45°C. Double and triple mutation constructs ...
