The endopolyphosphatase gene: essential in Saccharomyces cerevisiae.
Sorting of proteins into multivesicular bodies: ubiquitin-dependent and -independent targeting.
Purification and properties of exopolyphosphatase from the cytosol of Saccharomyces cerevisiae not encoded by the PPX1 gene.
Endopolyphosphatase in Saccharomyces cerevisiae undergoes post-translational activations to produce short-chain polyphosphates.
Inorganic polyphosphate and exopolyphosphatase in the nuclei of Saccharomyces cerevisiae: dependence on the growth phase and inactivation of the PPX1 and PPN1 genes.
High molecular mass exopolyphosphatase from the cytosol of the yeast Saccharomyces cerevisiae is encoded by the PPN1 gene.
Polyphosphatase PPN1 of Saccharomyces cerevisiae: switching of exopolyphosphatase and endopolyphosphatase activities.

Purified recombinant Ppn1 favors terminal phosphate release in Co2+ and internal polyphosphate fragmentation in Mg2+.
"Thus, the exopolyphosphatase activity of PPN1 prevailed in the presence of Co2+, while the endopolyphosphatase activity prevailed in the presence of Mg2+."
One library to make them all: streamlining the creation of yeast libraries via a SWAp-Tag strategy.
Ppn2 endopolyphosphatase overexpressed in Saccharomyces cerevisiae: Comparison with Ppn1, Ppx1, and Ddp1 polyphosphatases.
A systematic study of regulating inorganic polyphosphates production in Saccharomyces cerevisiae.

A 55-gene knockout screen found ppn1 among the deletions that elevate cellular polyphosphate and used Δppn1 as the base for double-knockout engineering of long-chain polyP production.
"Through screening a library of 55 single-gene knockout strains, we identified six mutants (Δddp1, Δvip1, Δppn1, Δppn2, Δecm33, and Δccr4) exhibiting elevated polyP accumulation"
A screening approach unveils an unknown Mn(2+)-dependent endopolyphosphatase activity in yeast.
-
The FRET-polyP8 assay paper treats Ppn1 as one of the known yeast endopolyphosphatases and then detects an additional Mn2+-dependent endopolyphosphatase activity in a quadruple mutant.
"In yeast, three endopolyphosphatases have been identified: (1) the vacuolar PPN1, which exhibits both exo- and endopolyphosphatase activity"
