RNase P — a ‘Scarlet Pimpernel’ [PDF]
RNase P is responsible for the maturation of the 5′‐termini of tRNA molecules in all cells studied to date. This ribonucleoprotein has to recognize and identify its cleavage site on a large number of different precursors. This review covers what is currently known about the function of the catalytic subunit of Escherichia coli RNase P, M1 RNA, and the ...

RNA synthesis in mitochondria isolated from rat liver [PDF]
Mitochondrial RNA (mtRNA) was synthesized from purine and pyrimidine nucleosides in coupling with oxidative phosphorylation using isolated mitochondria. The in vivo synthesized mtRNA was adenine-uracil rich and sedimented at about 20 S by sucrose density

RNase MRP and RNase P share a common substrate
RNase MRP is a site-specific ribonucleoprotein endoribonuclease that processes RNA from the mammalian mitochondrial displacement loop containing region. RNase P is a site-specific ribonucleoprotein endoribonuclease that processes pre-tRNAs to generate their mature 5'-ends.

Ribonuclease P (RNase P) is a class of enzymes involved in the processing of precursor tRNAs to remove their 5'-leader sequences. Ribonuclease P enzymes are classified into two completely distinct classes, i.e.

Comparative Analysis of Ribonuclease P RNA of the Planctomycetes [PDF]
The planctomycetes, order Planctomycetales, are a distinct phylum of domain Bacteria. Genes encoding the RNA portion of ribonuclease P (RNase P) of some planctomycete members were sequenced and compared with existing database planctomycete sequences ...

Archaeal RNase P has multiple protein subunits homologous to eukaryotic nuclear RNase P proteins [PDF]
Although archaeal RNase P RNAs are similar in both sequence and structure to those of Bacteria rather than eukaryotes, and heterologous reconstitution between the Bacillus subtilis RNase P protein and some archaeal RNase P RNAs has been demonstrated, no archaeal protein sequences with similarity to any known bacterial RNase P protein subunit have been ...

A Novel Method to Isolate RNase MRP Using RNA Streptavidin Aptamer Tags
Interactions between RNA-binding proteins and RNA molecules are at the center of multiple biological processes. Therefore, accurate characterization of the composition of ribonucleoprotein complexes (RNPs) is crucial.

EXOSC10 is required for RPA assembly and controlled DNA end resection at DNA double-strand breaks [PDF]
The exosome is a ribonucleolytic complex that plays important roles in RNA metabolism. Here we show that the exosome is necessary for the repair of DNA double-strand breaks (DSBs) in human cells and that RNA clearance is an essential step in homologous ...

The RNase P family is a diverse group of endonucleases responsible for the removal of 5' extensions from tRNA precursors. The diversity of enzyme forms finds its extremes in the eukaryal nucleus where RNA-based catalysis by complex ribonucleoproteins in ...

Human RNase H1 is associated with protein P32 and is involved in mitochondrial pre-rRNA processing. [PDF]
Mammalian RNase H1 has been implicated in mitochondrial DNA replication and RNA processing and is required for embryonic development. We identified the mitochondrial protein P32 that binds specifically to human RNase H1, but not human RNase H2. P32 binds
