[Inactivation of the ppn1 gene exerts different effects on the metabolism of inorganic polyphosphates in the cytosol and the vacuoles of the yeast Saccharomyces cerevisiae].

Abstract excerpt

Inactivation of the PPN1 gene, encoding one of the enzymes involved in polyphosphate metabolism in the yeast Saccharomyces cerevisiae, was found to decrease exopolyphosphatase activity in the cytosol and vacuoles. This effect was more pronounced in the stationary growth phase than in the phase of active growth. The gene inactivation resulted in elimination of a approximately 440-kDa exopolyphosphatase in the...
