Is alba an RNase P subunit? [PDF]
It has been suggested that Alba, a well-established chromatin protein in Archaea, is also a subunit of the archaeal RNase P holoenzyme, based on the observation that the homolog of this protein in humans has been shown to be associated with RNase P activity.

Difference between Mitochondrial RNase P and Nuclear RNase P [PDF]
We previously demonstrated that mammalian cells contain at least two distinct RNase P activities, one nuclear and one mitochondrial (5, 7). These enzymes were shown to have different substrate specificities and distinct molecular and enzymatic properties (5–7).

Function and assembly of a chromatin-associated RNase P that is required for efficient transcription by RNA polymerase I. [PDF]
Human RNase P has been initially described as a tRNA processing enzyme, consisting of H1 RNA and at least ten distinct protein subunits. Recent findings, however, indicate that this catalytic ribonucleoprotein is also required for transcription of small ...

The catalytic core of RNase P [PDF]
A deletion mutant of the catalytic RNA component of Escherichia coli RNase P missing residues 87-241 retains the ability to interact with the protein component to form a functional catalyst. The deletion of this phylogenetically conserved region significantly increases the Km, indicating that the deleted structures may be important for binding to the ...

Crystallization and crystallographic analysis of an Arabidopsis nuclear proteinaceous RNase P [PDF]
RNase P activity is ubiquitous and involves the 5' maturation of precursor tRNAs. For a long time, it was thought that all RNases P were ribonucleoproteic enzymes.

Zebrafish RNase T2 genes and the evolution of secretory ribonucleases in animals
Background Members of the Ribonuclease (RNase) T2 family are common models for enzymological studies, and their evolution has been well characterized in plants.

Evolution of ribonuclease H genes in prokaryotes to avoid inheritance of redundant genes
Background A theoretical model of genetic redundancy has proposed that the fates of redundant genes depend on the degree of functional redundancy, and that functionally redundant genes will not be inherited together.

Architecture and Function of the Human Endonucleases RNase P and RNase MRP [PDF]
AbstractIn the past decade, important advances have been made in our knowledge of the composition of human RNase MRP and RNase P complexes. Both ribonucleoprotein particles function as endonucleases and contain RNA components that are structurally related.

Genetic diversity of human RNase 8
Background Ribonuclease 8 is a member of the RNase A family of secretory ribonucleases; orthologs of this gene have been found only in primate genomes. RNase 8 is a divergent paralog of RNase 7, which is lysine-enriched, highly conserved, has prominent ...

P finder: genomic and metagenomic annotation of RNase P RNA gene (rnpB)
Background The rnpB gene encodes for an essential catalytic RNA (RNase P). Like other essential RNAs, RNase P’s sequence is highly variable. However, unlike other essential RNAs (i.e.
