The key regulatory enzyme in gluconeogenesis, fructose 1,6-bisphosphatase (FBPase) is subject to glucose-stimulated proteolytic degradation in Saccharomyces cerevisiae. This process involves the regulated transfer of FBPase directly from the cytosol into the vacuole or a vacuole-related organelle. Glucose may regulate the production of an FBPase receptor or import factor that is transported to the vacuole through the secretory pathway.
