Nitrogen coordinated import and export of arginine across the yeast vacuolar membrane.
The vacuole of the yeast Saccharomyces cerevisiae plays Cosmetic an important role in nutrient storage.Arginine, in particular, accumulates in the vacuole of nitrogen-replete cells and is mobilized to the cytosol under nitrogen starvation.The arginine import and export systems involved remain poorly characterized, however.Furthermore, how their act
