Fructose-1,6-bisphosphatase, Malate Dehydrogenase, Isocitrate Lyase, Phosphoenolpyruvate Carboxykinase, Glyceraldehyde-3-phosphate Dehydrogenase, and Cyclophilin A are secreted inSaccharomyces cerevisiaegrown in low glucose

Our previous studies demonstrated that the key gluconeogenic enzyme fructose-1,6-bisphosphatase is secreted when Saccharomyces cerevisiae are starved of glucose for a prolonged period of time. In this study, we showed that malate dehydrogenase, isocitrate lyase, phosphoenolpyruvate carboxykinase, glyceraldehyde-3-phosphate dehydrogenase, and cyclophilin A are also secreted in glucose-starved cells. Thus, both gluconeogenic and non-gluconeogenic enzymes are secreted via the non-classical pathway.
