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

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