Exopolyphosphatases of the yeast Saccharomyces cerevisiae.
Separate compartments of the yeast cell possess their own exopolyphosphatases differing from each other in their properties and dependence on culture conditions. The low-molecular-mass exopolyphosphatases of the cytosol, cell envelope, and mitochondrial matrix are encoded by the PPX1 gene, while the high-molecular-mass exopolyphosphatase of the cytosol and those of the vacuoles, mitochondrial membranes, and nuclei are presumably encoded by their own genes. Based on recent works, a preliminary classification of the yeast exopolyphosphatases is proposed.
