additional information inactivation of the PPX1 gene has no effect on the polyP metabolism under cultivation of the yeast in medium with glucose and phosphate, while inactivation of the PPN1 gene results in elimination of the high-molecular-mass exopolyphosphatases of the cytosol, nuclei, vacuoles, and mitochondria of Saccharomyces cerevisiae, PPN1 inactivation has negligible effect on polyP levels, it results in increase in the long-chain polyPs in all the compartments under study Saccharomyces cerevisiae
