Cryo-electron microscopy structure of an archaeal ribonuclease P holoenzyme [PDF]
Ribonulease P is a conserved ribozyme present in all kingdoms of life that is involved in the 5′ maturation step of tRNAs. Here the authors determine the structure of an archaeal RNase P holoenzyme that reveals how archaeal RNase P recognizes its tRNA ...

The gene coding for the RNA subunit of ribonuclease P (RNase P) is essential in all free-living organisms. The RNA subunit, itself, is an enzyme and, from its evolutionary tree, we can infer that it is a very ancient molecule. The specificity of this enzyme is that it cleaves other RNA molecules at the junction of single-stranded and the 5′ end of ...

Structural basis for protein-free catalysis by ribonuclease P ribozyme [PDF]
Ribonuclease P (RNase P) is an essential metallonuclease found in all three domains of life. However, the structural basis for the ancient RNase P RNA component acting alone as a ribozyme and catalytic metal-ion chemistry remains unknown.

The Diversity of Ribonuclease P: Protein and RNA Catalysts with Analogous Biological Functions [PDF]
Ribonuclease P (RNase P) is an essential endonuclease responsible for catalyzing 5’ end maturation in precursor transfer RNAs. Since its discovery in the 1970s, RNase P enzymes have been identified and studied throughout the three domains of life ...

Safety evaluation of the food enzyme ribonuclease P from the non‐genetically modified Penicillium citrinum strain AE‐RPE [PDF]
The food enzyme ribonuclease P (EC 3.1.26.5) is produced with the non‐genetically modified Penicillium citrinum strain AE‐RPE by Amano Enzyme Inc. It was considered free from viable cells of the production organism.

The specificity landscape of bacterial ribonuclease P [PDF]
Developing quantitative models of substrate specificity for RNA processing enzymes is a key step toward understanding their biology and guiding applications in biotechnology and biomedicine. Optimally, models to predict relative rate constants for alternative substrates should integrate an understanding of structures of the enzyme bound to "fast" and ...

Identification of the Acinetobacter baumannii Ribonuclease P Catalytic Subunit: Cleavage of a Target mRNA in the Presence of an External Guide Sequence [PDF]
The bacterial ribonuclease P or RNase P holoenzyme is usually composed of a catalytic RNA subunit, M1, and a cofactor protein, C5. This enzyme was first identified for its role in maturation of tRNAs by endonucleolytic cleavage of the pre-tRNA. The RNase

The ancient history of the structure of ribonuclease P and the early origins of Archaea [PDF]
Background 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).

Structure and Function of Eukaryotic Ribonuclease P RNA [PDF]
Ribonuclease P (RNase P) is the ribonucleoprotein endonuclease that processes the 5' ends of precursor tRNAs. Bacterial and eukaryal RNase P RNAs had the same primordial ancestor; however, they were molded differently by evolution. RNase P RNAs of eukaryotes, in contrast to bacterial RNAs, are not catalytically active in vitro without proteins.
