Genetic diversity of human RNase 8
Background Ribonuclease 8 is a member of the RNase A family of secretory ribonucleases; orthologs of this gene have been found only in primate genomes. RNase 8 is a divergent paralog of RNase 7, which is lysine-enriched, highly conserved, has prominent ...

Influence of Conformation of M. tuberculosis RNase P Protein Subunit on Its Function. [PDF]
RNase P is an essential enzyme that processes 5' end leader sequence of pre-tRNA to generate mature tRNA. The bacterial RNase Ps contain a RNA subunit and one protein subunit, where the RNA subunit contains the catalytic activity.

Insights into the structure and activity of prototype foamy virus RNase H
Background RNase H is an endonuclease that hydrolyzes the RNA strand in RNA/DNA hybrids. Retroviral reverse transcriptases harbor a C-terminal RNase H domain whose activity is essential for viral replication.

Cryo-EM structure of catalytic ribonucleoprotein complex RNase MRP
Ribozyme-based RNase MRP is an essential eukaryotic enzyme involved in the maturation of rRNA and is evolutionarily related to RNase P. Here, the authors present the 3.0 Å cryo-EM structure of the S.

Human serum RNase-L level is inversely associated with metabolic syndrome and age
Background Ribonuclease-L (RNase-L) was known to be a ubiquitous enzyme involved in several cellular functions, especially innate immunity. It was recently shown to participate in adipogenesis in rodents.

Antisense-Inhibition der bakteriellen RNase P [PDF]
Ziel der vorliegenden Arbeit war die in vitro- und in vivo-Inhibition bakterieller RNase P mit Antisense-Oligonukleotiden (AS-ON). RNase P ist ein essentielles Ribonukleoproteinenzym, das in allen drei Reichen des Lebens für die Reifung der ptRNAs ...

Evolution and thermodynamics of the slow unfolding of hyperstable monomeric proteins
Background The unfolding speed of some hyperthermophilic proteins is dramatically lower than that of their mesostable homologs. Ribonuclease HII from the hyperthermophilic archaeon Thermococcus kodakaraensis (Tk-RNase HII) is stabilized by its remarkably

Phosphatidic acid counteracts S-RNase signaling in pollen by stabilizing the actin cytoskeleton [PDF]
S-RNase is the female determinant of self-incompatibility (SI) in pear (Pyrus bretschneideri). After translocation to the pollen tube, S-RNase degrades rRNA and induces pollen tube death in an S-haplotype-specific manner. In this study, we found that the

Mouse ribonuclease III. cDNA structure, expression analysis, and chromosomal location
Background Members of the ribonuclease III superfamily of double-stranded(ds)-RNA-specific endoribonucleases participate in diverse RNA maturation and decay pathways in eukaryotic and prokaryotic cells. A human RNase III orthologue has been implicated in

Acid ribonuclease activity of hepatoma cells [PDF]
Activities of intracellular RNase of the liver cytoplasm, normal liver cells exposed to 3'-Me-DAB and heaptoma cells, have been studied in correlation with the contents of RNA and DNA and morphologic changes of the cells with or without treating RNase ...
