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 ...

Plant mitochondrial RNase P and E. coli RNase P have different substrate specificities.
Biochemistry and molecular biology international, 1993Substrate specificity requirements of the plant mitochondrial RNase P were investigated with different natural and mutated substrates. Heterologous precursors with intact tRNAs from plant and fungal mitochondria, from bacteria, archaebacteria and of eukaryotic origins were processed faithfully, albeit with different efficiencies.

Enzymatic RNA synthesis and RNase P
Molecular Biology Reports, 1996TransferRNA recognition was used as leit-motiv in the illustration of possible links between a hypothetical primordial RNA world and the contemporary DNA world. In an RNA world, 'proto-tRNA' could have functioned as replication origin and as primitive telomere.

In 1989, Sidney Altman and Thomas R. Cech shared the Nobel Prize in Chemistry for their discovery of catalytic properties of RNA. Cech was studying the splicing of RNA in a unicellular organism called Tetrahymena thermophila. He found that the precursor RNA could splice in vitro in the absence of proteins.
