Identification of Small‐Molecule Inhibitors of the XendoU Endoribonucleases Family
ChemMedChem, 2011 The XendoU family of enzymes includes several proteins displaying high sequence homology. The members characterized so far are endoribonucleases sharing similar biochemical properties and a common architecture in their active sites.

Regulation of 6S RNA biogenesis by switching utilization of both sigma factors and endoribonucleases
Nucleic Acids Research, 2004 In Escherichia coli, 6S RNA functions as a modulator of RNA polymerase sigma(70)-holoenzyme activity, but its biosynthetic pathway remains uncharacterized.

hPop5, a Protein Subunit of the Human RNase MRP and RNase P Endoribonucleases [PDF]
Journal of Biological Chemistry, 2001 The RNase MRP and RNase P particles both function as endoribonucleases. RNase MRP has been implicated in the processing of precursor-rRNA, whereas RNase P has been shown to function in the processing of pre-tRNA.

Chloroplast p54 Endoribonuclease
2001Publisher Summary Much of the regulation of chloroplast gene expression has been assigned to stability determinants at the level of RNA precursors, including interactions of sequence and/or structural elements with their cognate binding proteins. A number of these proteins are known to assemble at the 5′-untranslated region (UTR) of chloroplast mRNAs,

Influenza Virus Endoribonuclease
2001The influenza virus polymerase complex contains two associated enzymatic activities, an endoribonuclease and a RNA-dependent RNA polymerase activity. Both activities have so far been observed only with the complete polymerase complex consisting of three subunits, PB1, PB2, and PA.

Leishmaniaviruses (LRV) are double-stranded RNA viruses that persistently infect some strains of the protozoan parasite Leishmania. The identification of a short viral RNA transcript led to our discovery of an endoribonuclease activity of the LRV capsid protein.

The role of endoribonucleases in the regulation of RNase R
Biochemical and Biophysical Research Communications, 2006RNase R is an important exoribonuclease involved in the maturation and degradation of RNA. RNase R is co-transcribed with other genes in the same operon. In this report, we show that under physiological conditions maturation of these co-transcripts and the levels of RNase R are mainly dependent on the endoribonuclease RNase E.

Purification and characterization of a novel mammalian endoribonuclease
Journal of Cellular Biochemistry, 2005AbstractEndonuclease‐mediated mRNA decay appears to be a common mode of mRNA degradation in mammalian cells, but yet only a few mRNA endonucleases have been described. Here, we report the existence of a second mammalian endonuclease that is capable of cleaving c‐myc mRNA within the coding region in vitro.

Endoribonuclease activities of Trypanosoma brucei mitochondria
Molecular and Biochemical Parasitology, 2002RNA editing in kinetoplastids is a type of post-transcriptional processing that changes mitochondrial mRNA sequences by the addition or deletion of uridines. Multiple enzymatic activities, such as endoribonuclease and RNA ligase, are associated with this process and exist in a multienzyme complex.
