Inactivation of endopolyphosphatase gene PPN1 results in inhibition of expression of exopolyphosphatase PPX1 and high-molecular-mass exopolyphosphatase not encoded by PPX1 in Saccharomyces cerevisiae.

Abstract excerpt

Saccharomyces cerevisiae possesses multiple forms of exopolyphosphatases, the enzymes involved in the metabolism of inorganic polyphosphates, which are important regulatory compounds. In S. cerevisiae, inactivation of endopolyphosphatase gene PPN1 leads to the inhibition of expression of both exopolyphosphatase PPX1 and high-molecular-mass exopolyphosphatase of approximately 1000 kDa not encoded by PPX1. In the...
