Pyrazinamide (PZA) is a key drug for tuberculosis treatment. The active form of PZA, pyrazinoic acid (POA), appears to inhibit multiple targets in M. tuberculosis. Recently, the bifunctional enzyme Rv2783 was reported as a new target of POA. However, the

Identification of Genes Potentially Regulated by Human Polynucleotide Phosphorylase (hPNPaseold-35) Using Melanoma as a Model [PDF]
Human Polynucleotide Phosphorylase (hPNPaseold-35 or PNPT1) is an evolutionarily conserved 3′→5′ exoribonuclease implicated in the regulation of numerous physiological processes including maintenance of mitochondrial homeostasis, mtRNA import and aging ...

Overexpression of a natural chloroplast-encoded antisense RNA in tobacco destabilizes 5S rRNA and retards plant growth [PDF]
Background The roles of non-coding RNAs in regulating gene expression have been extensively studied in both prokaryotes and eukaryotes, however few reports exist as to their roles in organellar gene regulation.

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 ...

Stable PNPase RNAi silencing: Its effect on the processing and adenylation of human mitochondrial RNA [PDF]
Polynucleotide phosphorylase (PNPase) is a diverse enzyme, involved in RNA polyadenylation, degradation, and processing in prokaryotes and organelles. However, in human mitochondria, PNPase is located in the intermembrane space (IMS), where no mitochondrial RNA (mtRNA) is known to be present.

Transcription of the human mitochondrial genome produces a vast amount of non-coding antisense RNAs. These RNA species can form G-quadraplexes (G4), which affect their decay. We found that the mitochondrial degradosome, a complex of RNA helicase SUPV3L1 (

Investigation of IFN signaling in cultured skin fibroblasts from patients with genetically confirmed mitochondrial diseases of diverse origins revealed that altered IFN signaling is an inconsistent feature of these disorders. Cytosolic accumulation of mtDNA and mtRNA was variably detected and showed little correlation with ISG scores.
