Human Polynucleotide Phosphorylase, hPNPase, is Localized in Mitochondria
Journal of Molecular Biology, 2003 The human gene encoding a polynucleotide phosphorylase (hPNPase) has been recently identified as strongly up-regulated in two processes leading to irreversible arrest of cell division: progeroid senescence and terminal differentiation. Here, we demonstrate that the hPNPase is localized in mitochondria.

Polynucleotide Phosphorylase and the T3SS
, 2007 Low temperatures as well as encounters with host phagocytes are two stresses that have been relatively well studied in many species of bacteria. The exoribonuclease polynucleotide phosphorylase (PNPase) has previously been shown to be required by several species of bacteria, including Yersinia, for low-temperature growth. We have shown that PNPase also

Photometric Assay for Polynucleotide Phosphorylase
Analytical Biochemistry, 1999Polynucleotide phosphorylase (PNPase) is a prokaryotic enzyme that catalyzes phosphorolysis of polynucleotides with release of NDPs. It is also believed to play a key role in turnover of prokaryotic transcripts, thus regulating gene expression. At the moment, only radioisotopic methods are available for assaying PNPase in crude extracts; these involve ...

Polynucleotide phosphorylase-based photometric assay for inorganic phosphate
Analytical Biochemistry, 2004 Polynucleotide phosphorylase is a prokaryotic enzyme that catalyzes phosphorolysis of polynucleotides with release of nucleotide diphosphates. By taking advantage of this property, we developed a photometric assay for inorganic phosphate. In the presence

A novel RNA digesting activity from commercial polynucleotide phosphorylase [PDF]
FEBS Letters, 1985 RNase A4 is a new RNase activity found as a contaminant in commercial polynucleotide phosphorylase. This enzyme has the ability of hydrolyzing the phosphodiester bond between pyrimidine-A in both loop and paired regions of ...
