The RNase P ofDictostyelium discoideum
Molecular Biology Reports, 1996Ribonuclease P (RNase P) is a key enzyme involved in tRNA biosynthesis. It catalyses the endonucleolytic cleavage of nearly all tRNA precursors to produce 5'-end matured tRNA. RNase P activity has been found in all organisms examined, from bacteria to mammals.

Characterization of RNase P RNA Activity
2012The principle task of the ubiquitous enzyme RNase P is the generation of mature tRNA 5'-ends by removing precursor sequences from tRNA primary transcripts (Trends Genet 19:561-569, 2003; Crit Rev Biochem Mol Biol 41:77-102, 2006; Trends Biochem Sci 31:333-341, 2006).

Further characterization of human RNase MRP/RNase P and related autoantibodies
Molecular Biology Reports, 1998We characterized a panel of human RNase MRP/RNase P autoantibodies by immunoprecipitation, immunodepletion, immunoaffinity purification and immunoblotting. We report on the protein spectrum that is recognized by RNase MRP/RNase P autoantibodies. We also describe another, related patient serum that based on these assays does not immunoprecipitate RNase ...

Yeast mitochondrial RNase P: an unusual member of the RNase P enzyme family
1995We review here our studies of the tRNA processing enzyme, RNase P. Yeast mitochondrial RNase P contains an AU-rich mitochondrial coded RNA which varies in size in different yeasts. All of these RNAs contain two short sequences with similarity to two sequences found in all RNase P RNAs.

RNase P is an almost universal enzyme present in Bacteria, Archaea and Eukaryotic nuclei, as well as in mitochondria and chloroplasts. The organellar enzyme shows a great variability in structure and composition. A gene encoding an RNA, homologous to bacterial catalytic RNase P RNA, is found in mitochondria of a diversity of organisms that include ...

Human RNase P and Transcription
2009Human nuclear RNase P has been initially characterized by virtue of its ability to process the 5′ leader sequence of precursor tRNA. This ribonucleoprotein complex consists of H1 RNA subunit and at least ten distinct protein components. However, recent findings reveal that RNase P has a role in transcription by RNA polymerase I (Pol I) and Pol III ...

Modular organization of RNase P
2008Ribonuclease P (RNase P) is a ribozyme that removes the 5′ precursor sequence from premature t-RNAs. In bacteria this complex consists of one RNA subunit and a single protein subunit, whereas in eukaryotes one RNA subunit and nine protein subunits contribute. We have determined the structure of eukaryotic RNase P at ca. 15 ?

This chapter is primarily a progress report on work with the enzyme from Escherichia coli. RNase P, the endonuclease responsible for the biosynthesis of the 5' termini of mature tRNA, is a ribonucleoprotein. The chapter primarily focuses on relationships between the structure and function of the subunits of RNase P, as determined from studies with the ...
