Decay-Initiating Endoribonucleolytic Cleavage by RNase Y Is Kept under Tight Control via Sequence Preference and Sub-cellular Localisation. [PDF]
Bacteria depend on efficient RNA turnover, both during homeostasis and when rapidly altering gene expression in response to changes. Nevertheless, remarkably few details are known about the rate-limiting steps in targeting and decay of RNA.

Three essential ribonucleases-RNase Y, J1, and III-control the abundance of a majority of Bacillus subtilis mRNAs. [PDF]
Bacillus subtilis possesses three essential enzymes thought to be involved in mRNA decay to varying degrees, namely RNase Y, RNase J1, and RNase III. Using recently developed high-resolution tiling arrays, we examined the effect of depletion of each of ...

Escherichia coli RNase E can efficiently replace RNase Y in Bacillus subtilis. [PDF]
AbstractRNase Y and RNase E are disparate endoribonucleases that govern global mRNA turnover/processing in the two evolutionary distant bacteria Bacillus subtilis and Escherichia coli, respectively. The two enzymes share a similar in vitro cleavage specificity and subcellular localization.

Interaction of Bacillus subtilis Polynucleotide Phosphorylase and RNase Y: STRUCTURAL MAPPING AND EFFECT ON mRNA TURNOVER. [PDF]
Polynucleotide phosphorylase (PNPase), a 3'-to-5' phosphorolytic exoribonuclease, is thought to be the primary enzyme responsible for turnover ofBacillus subtilismRNA. The role of PNPase inB. subtilismRNA decay has been analyzed previously by comparison of mRNA profiles in a wild-type strainversusa strain that is deleted forpnpA, the gene encoding ...

RNase Y-mediated regulation of the streptococcal pyrogenic exotoxin B. [PDF]
Endoribonuclease Y (RNase Y) is a crucial regulator of virulence in Gram-positive bacteria. In the human pathogen Streptococcus pyogenes, RNase Y is required for the expression of the major secreted virulence factor streptococcal pyrogenic exotoxin B (SpeB), but the mechanism involved in this regulation remains elusive. Here, we demonstrate that the 5′

Role of RNase Y in Clostridium perfringens mRNA Decay and Processing. [PDF]
ABSTRACT RNase Y is a major endoribonuclease that plays a crucial role in mRNA degradation and processing. We study the role of RNase Y in the Gram-positive anaerobic pathogen Clostridium perfringens , which until now has not been well understood.

Quasi-essentiality of RNase Y in Bacillus subtilis is caused by its critical role in the control of mRNA homeostasis. [PDF]
Abstract RNA turnover is essential in all domains of life. The endonuclease RNase Y (rny) is one of the key components involved in RNA metabolism of the model organism Bacillus subtilis. Essentiality of RNase Y has been a matter of discussion, since deletion of the rny gene is possible, but leads to severe phenotypic effects.

Multiple roles of RNase Y in Streptococcus pyogenes mRNA processing and degradation. [PDF]
ABSTRACT Control over mRNA stability is an essential part of gene regulation that involves both endo- and exoribonucleases. RNase Y is a recently identified endoribonuclease in Gram-positive bacteria, and an RNase Y ortholog has been identified in Streptococcus pyogenes (group A streptococcus [GAS]).

Downstream element determines RNase Y cleavage of the saePQRS operon in Staphylococcus aureus. [PDF]
In gram-positive bacteria, RNase J1, RNase J2 and RNase Y are thought to be major contributors to mRNA degradation and maturation. In Staphylococcus aureus, RNase Y activity is restricted to regulating the mRNA decay of only certain transcripts. Here the saePQRS operon was used as a model to analyze RNase Y specificity in living cells.
