Interaction of Bacillus subtilis Polynucleotide Phosphorylase and RNase Y: STRUCTURAL MAPPING AND EFFECT ON mRNA TURNOVER. [PDF]

open access: yesJ Biol Chem, 2016
Polynucleotide phosphorylase (PNPase), a 3′-to-5′ phosphorolytic exoribonuclease, is thought to be the primary enzyme responsible for turnover of Bacillus subtilis mRNA. The role of PNPase in B.

Localization of components of the RNA-degrading machine in Bacillus subtilis [PDF]

open access: yesFrontiers in Microbiology, 2016
In bacteria, the control of mRNA stability is crucial to allow rapid adaptation to changing conditions. In most bacteria, RNA degradation is catalyzed by the RNA degradosome, a protein complex composed of endo- and exoribonucleases, RNA helicases and ...

Study on the structure-function relationship of polynucleotide phosphorylase: model of a proteolytic degraded polynucleotide phosphorylase [PDF]

open access: bronzeNucleic Acids Research, 1976
It is already known that modification of E. coli polynucleotide phosphorylase by endogenous proteolysis induces drastic changes in both phosphorolysis and polymerisation reactions. The structural parameters of the proteolysed polynucleotide phosphorylase are described.

Oocyte Factors Suppress Mitochondrial Polynucleotide Phosphorylase to Remodel the Metabolome and Enhance Reprogramming

open access: yesCell Reports, 2015
Oocyte factors not only drive somatic cell nuclear transfer reprogramming but also augment the efficiency and quality of induced pluripotent stem cell (iPSC) reprogramming.

RNase E forms a complex with polynucleotide phosphorylase in cyanobacteria via a cyanobacterial-specific nonapeptide in the noncatalytic region. [PDF]

open access: yesRNA, 2014
The endoribonuclease RNase E in a range of bacteria has a conserved N-terminal catalytic domain and a less well-conserved C-terminal tail. While the role of the C-terminal tail in the formation of the degradosome, including the interaction with the ...

Crystal structure of Caulobacter crescentus polynucleotide phosphorylase reveals a mechanism of RNA substrate channelling and RNA degradosome assembly [PDF]

open access: yesOpen Biology, 2012
Polynucleotide phosphorylase (PNPase) is an exoribonuclease that cleaves single-stranded RNA substrates with 3′–5′ directionality and processive behaviour.

Helicase SUV3, polynucleotide phosphorylase, and mitochondrial polyadenylation polymerase form a transient complex to modulate mitochondrial mRNA polyadenylated tail lengths in response to energetic changes. [PDF]

open access: yesJ Biol Chem, 2014
Background: Helicase SUV3, polynucleotide phosphorylase (PNPase), or mitochondrial poly(A) polymerases (mtPAP) have individual activity in regulating mitochondrial mRNA (mt-mRNA)-polyadenylated (poly(A)) tails.
