Eukaryote RNase P and RNase MRP
, 2010Ribonuclease P (RNase P) is an essential endonuclease that catalyzes the cleavage of the 5′ leader sequence from precursor tRNAs (pre-tRNAs). Most forms of RNase P are ribonucleoproteins and the bacterial enzyme possesses a single catalytic RNA and one small protein.

The RNA processing enzyme RNase MRP is identical to the Th RNP and related to RNase P. [PDF]
Science, 1989 Sera from patients with autoimmune diseases often contain antibodies that bind ribonucleoproteins (RNPs). Sera from 30 such patients were found to immunoprecipitate ribonuclease P (RNase P), an RNP enzyme required to process the 5' termini of transfer ...

Definition of the Th/ To ribonucleoprotein by RNase P and RNase MRP [PDF]
Molecular Biology Reports, 1993 We show that the Th/To ribonucleoprotein is defined by (i) the co-immunoprecipitation of two RNAs, (ii) the co-immunoprecipitation of four major polypeptides and (iii) the quantitative immune recognition of both RNase P and RNase MRP. No serum was found that recognizes either one of these two enzymes exclusively.

RNase MRP is a ribonucleoprotein enzyme with a structure similar to RNase P. It is required for normal processing of precursor rRNA, cleaving it in the Internal Transcribed Spacer 1.

AbstractRNase MRP and RNase P ribonucleoproteins are structurally and functionally similar across a large evolutionary distance. To better characterize possible complex interrelationships between these two enzymes, we have employed the fission yeast Schizosaccharomyces pombe. Unlike Saccharomyces cerevisiae, S.

A novel protein shared by RNase MRP and RNase P
RNA (New York, N.Y.), 1997We have isolated suppressors of the temperature-sensitive rRNA processing mutation rrp2-2 in Saccharomyces cerevisiae. A class of extragenic suppressors was mapped to the YBR257w reading frame in the right arm of Chromosome II. Characterization of this gene, renamed POP4, shows that the gene product is necessary both for normal 5.8S rRNA processing and

Probing the structure of Saccharomyces cerevisiae RNase MRP
Biochemical Society Transactions, 2005In yeast, RNase MRP (mitochondrial RNA processing), a ribonucleoprotein precursor rRNA processing enzyme, possesses one putatively catalytic RNA and ten protein subunits and is highly related to RNase P. Structural analysis of the MRP RNA provides data that closely match a previous secondary-structure model derived from phylogenetic analysis, with the ...
