We have used model substrates carrying modified nucleotides at the site immediately 5 of the canonical RNase P cleavage site, the -1 position, to study Escherichia coli RNase P RNA-mediated cleavage. We show that the nucleobase at -1 is not essential but its presence and identity contribute to efficiency, fidelity of cleavage and stabilization of the transition state. When U or C is present at -1, the carbonyl oxygen at C2 on the nucleobase contributes to transition-state stabilization, and thus acts as a positive determinant. For substrates with purines at -1, an exocyclic amine at C2 on the nucleobase promotes cleavage at an alternative site and it has a negative impact on cleavage at the canonical site. We also provide new insights into the interaction between E. coli RNase P RNA and the -1 residue in the substrate. Our findings will be discussed using a model where bacterial RNase P cleavage proceeds through a conformational-assisted mechanism that positions the metal(II)-activated H2O for ...

Ribonuclease P is an ancient endonuclease that cleaves precursor tRNA and generally consists of a catalytic RNA subunit (RPR) and one or more proteins (RPPs). It represents an important macromolecular complex and model system that is universally distributed in life. Its putative origins have inspired fundamental hypotheses, including the proposal of an ancient RNA world. To study the evolution of this complex, we constructed rooted phylogenetic trees of RPR molecules and substructures and estimated RPP age using a cladistic method that embeds structure directly into phylogenetic analysis. The general approach was used previously to study the evolution of tRNA, SINE RNA and 5S rRNA, the origins of metabolism, and the evolution and complexity of the protein world, and revealed here remarkable evolutionary patterns. Trees of molecules uncovered the tripartite nature of life and the early origin of archaeal RPRs. Trees of substructures showed molecules originated in stem P12 and were accessorized with a

Distinct modes of mature and precursor tRNA binding to Escherichia coli RNase P RNA revealed by NAIM analyses.: We have analyzed by nucleotide analog interferen
M1 RNA, the catalytic component of Escherichia coli RNase P, is derived by 3` processing from pM1 RNA, a major transcript of the rnpB gene. This 3` processing occurs by two pathways involving multiple steps. The pM1 RNA molecule has an rne-dependent site downstream of the processing site, GAUUU, whose sequence variation affects the processing efficiency. In this thesis, first, roles of the sequence of the rne-dependent site on the pathways of 3` processing of M1 RNA were examined. The results showed that the primary sequence itself of the rne-dependent site possessed the ability to determine the processing pathways. Therefore, the sequence of the rne-dependent site seems not only to affect the processing efficiency, but also to guide the RNA metabolic pathway. The sequence of the rne-dependent site also affected the substrate specificity by generating the processing products at one nucleotide upstream or downstream from the normal cleavage sites. Interestingly, in case of the variants involving ...

Major progress in the study of RNase P has resulted from crystallography of bacterial catalytic subunits and the discovery of catalytic activity in eukaryotes. Several new substrates have also been identified, primarily in bacteria but also in yeast. Our current world should be called the
Abstract:. The dissemination of AAC(6)-I-type acetyltransferases have rendered amikacin and other aminoglycosides all but useless in some parts of the world. Antisense technologies could be an alternative to extend the life of these antibiotics. External guide sequences are short antisense oligoribonucleotides that induce RNase P-mediated cleavage of a target RNA by forming a precursor tRNA-like complex. Thirteen-nucleotide external guide sequences complementary to locations within five regions accessible for interaction with antisense oligonucleotides in the mRNA that encodes AAC(6)-Ib were analyzed. While small variations in the location targeted by different external guide sequences resulted in big changes in efficiency of binding to native aac(6)-Ib mRNA, most of them induced high levels of RNase P-mediated cleavage in vitro. Recombinant plasmids coding for selected external guide sequences were introduced into Escherichia coli harboring aac(6)-Ib, and the transformant strains were ...
Sidney Altman (1939 - present) was awarded half the 1989 Nobel Prize in Chemistry for his discovery of catalytic properties of RNA. Working separately from fellow Nobel Laureate Thomas R. Cech, Altman experimented with ribonuclease P (RNase P), an enzyme that catalyzes the breakdown of RNA into smaller components, and showed that the RNA component of RNase P was sufficient for its observed catalytic activity. This meant that the RNA itself had catalytic properties. Before this finding, it was believed that that protein subunit of RNase P was responsible for catalysis. RNase P also exists in eukaryotic organisms, and Altman later discovered that the protein subunits of eukaryotic Rnase P are essential to its catalytic activity, in contrast to the bacterial RNase P. ...
RNase P, a ribozyme-based ribonucleoprotein (RNP) complex that catalyzes tRNA 5′-maturation, is ubiquitous in all domains of life, but the evolution of its protein components (RNase P proteins, RPPs) is not well understood. Archaeal RPPs may provide clues on how the complex evolved from an ancient ribozyme to an RNP with multiple archaeal and eukaryotic (homologous) RPPs, which are unrelated to the single bacterial RPP. Here, we analyzed the sequence and structure of archaeal RPPs from over 600 available genomes. All five RPPs are found in eight archaeal phyla, suggesting that these RPPs arose early in archaeal evolutionary history. The putative ancestral genomic loci of archaeal RPPs include genes encoding several members of ribosome, exosome, and proteasome complexes, which may indicate coevolution/coordinate regulation of RNase P with other core cellular machineries. Despite being ancient, RPPs generally lack sequence conservation compared to other universal proteins. By analyzing the relative
RNase P, a ribonucleoprotein responsible for the 5´ maturation of precursor tRNAs (ptRNAs) in all organisms, can be enticed to cleave any target mRNA that forms a ptRNA-like structure and sequence-specific complex when bound to an RNA, termed the EGS (external guide sequence). In the present study, F3H (flavanone 3-hydroxylase), a key enzyme in the flavonoid biosynthetic pathway that participates in the formation of red-coloured anthocyanins, was used as a target for RNase P-mediated gene disruption in maize cells. Transient expression of an EGS complementary to the F3H mRNA resulted in suppression of F3H to 29% of the control, as indicated by a reduced number of anthocyanin-accumulating cells. This decrease was not observed in experiments where a disabled mutant EGS was expressed. Our results demonstrate the potential of employing plant RNase P, in the presence of an appropriate gene-specific EGS, as a tool for targeted degradation of mRNAs.. ...

So the subject of this lecture is RNase P in the other branch of life on Earth; the Archaea. The Archaea are a group of prokaryotic organisms that are really independent of the Bacteria, and if anything are more closely related geneologically to the eukaryotes (Eukarya) than to the Bacteria. In addition to being a distinct group, they are generally primative. In many ways, the molecular biology of the Archaea probably resembles those of the ancestors of the eukaryotes, and have proven to be very useful in sorting out the simpler roots of modern eukaryotic complexity.. ...
The entire human (hg38) genome was scanned for the -NGG motif. Flanking 20mer guide sequences were aligned to the genome with BWA and scored with MIT Specificity scores using the command-line version of crispor.org. Non-unique guide sequences were skipped. Flanking sequences were extracted from the genome and input for Crispor efficiency scoring, available from the Crispor downloads page, which includes the Doench 2016, Moreno-Mateos 2015 and Bae 2014 algorithms, among others.. Note that the Doench 2016 scores were updated by the Broad institute in 2017 ("Azimuth" update). As a result, earlier versions of the track show the old Doench 2016 scores and this version of the track shows new Doench 2016 scores. Old and new scores are almost identical, they are correlated to 0.99 and for more than 80% of the guides the difference is below 0.02. However, for very few guides, the difference can be bigger. In case of doubt, we recommend the new scores. Crispor.org can display both scores and many more ...

RNase E is an essential bacterial endoribonuclease involved in the turnover of messenger RNA and the maturation of structured RNA precursors in Escherichia coli. Here, we present the crystal structure of the E. coli RNase E catalytic domain in the apo-state at 3.3 A. This structure indicates that, upon catalytic activation, RNase E undergoes a marked conformational change characterized by the coupled movement of two RNA-binding domains to organize the active site. The structural data suggest a mechanism of RNA recognition and cleavage that explains the enzymes preference for substrates possessing a 5-monophosphate and accounts for the protective effect of a triphosphate cap for most transcripts. Internal flexibility within the quaternary structure is also observed, a finding that has implications for recognition of structured RNA substrates and for the mechanism of internal entry for a subset of substrates that are cleaved without 5-end requirements.
Since the discovery of catalytic RNA molecules (ribozymes), intense research has been devoted to understand their structure and activity. Among RNA molecules, the large ribozymes, namely group I and group II introns and RNase P, are of special importance. The first two ribozymes are known for their ability to perform self-splicing while RNase P is responsible for the 5′-end maturation of tRNA in bacteria, archea, and eukaryotes. All three groups of ribozymes show a significant requirement for metal ions in order to establish the active tertiary structure that enables catalysis. The primary role of both monovalent and divalent metal ions is to screen the negative charge associated with the phosphate sugar backbone, but the metal ions also play an active role in catalysis. Biochemical and biophysical investigations, supported by recent findings from X-ray crystal structures, allow clarifying and rationalizing both the structural and catalytic roles of metal ions in large ribozymes. In ...

The Ribonuclease A Superfamily is composed of a group of structurally similar peptides that are secreted by immune cells and epithelial tissues. Several members of the Ribonuclease A Superfamily demonstrate antimicrobial activity, and it has been suggested that some of these ribonucleases play an essential role in host defense. Ribonuclease 7 (RNase 7) is an epithelial-derived secreted peptide with potent broad-spectrum antimicrobial activity. This review summarizes the published literature on RNase 7s antimicrobial properties, structure, regulation, and contributions to host defense. In doing so, we conclude by highlighting key knowledge gaps that must be investigated to completely understand the potential of developing RNase 7 as a novel therapeutic for human infectious diseases.
