Abstract:
ABSTRACT 23S rRNA maturation in Bacillus subtilis is catalyzed by the recently characterized enzyme Mini-RNase-III. Mini-III is dispensable, however, and 23S rRNA is matured by other ribonucleases in strains lacking this enzyme. Here we show that these RNases are the 5′-to-3′ exoribonuclease RNase J1 and the 3′-to-5′ exoribonucleases, principally RNase PH and YhaM.

Abstract:
The regulation of RNA decay is now widely recognized as having a central role in bacterial adaption to environmental stress. Here we present an overview on the diversity of ribonucleases (RNases) and their impact at the posttranscriptional level in the human pathogenStaphylococcus aureus. RNases in prokaryotes have been mainly studied in the two model organismsEscherichia coliandBacillus subtilis. Based on identified RNases in these two models, putative orthologs have been identified inS. aureus. The main staphylococcal RNases involved in the processing and degradation of the bulk RNA are (i)

Abstract:
RNase J enzymes are metallohydrolases that are involved in RNA maturation and RNA recycling, govern gene expression in bacteria, and catalyze both exonuclease and endonuclease activity. The catalytic activity of RNase J is regulated by multiple mechanisms which include oligomerization, conformational changes to aid substrate recognition, and the metal cofactor at the active site. However, little is known of how RNase J paralogs differ in expression and activity. Here we describe structural and biochemical features of two Staphylococcus epidermidis RNase J paralogs, RNase J1 and RNase J2. RNase

Abstract:
Moonlighting proteins are proteins with more than one function. During the past 25 years, they have been found to be rather widespread in bacteria. In Bacillus subtilis, moonlighting has been disclosed to occur via DNA, protein or RNA binding or protein phosphorylation. In addition, two metabolic enzymes, enolase and phosphofructokinase, were localized in the degradosome-like network (DLN) where they were thought to be scaffolding components. The DLN comprises the major endoribonuclease RNase Y, 3′-5′ exoribonuclease PnpA, endo/5′-3′ exoribonucleases J1/J2 and helicase CshA. We have ascertaine

Abstract:
ABSTRACT rpsO mRNA, a small monocistronic mRNA that encodes ribosomal protein S15, was used to study aspects of mRNA decay initiation in Bacillus subtilis. Decay of rpsO mRNA in a panel of 3′-to-5′ exoribonuclease mutants was analyzed using a 5′-proximal oligonucleotide probe and a series of oligonucleotide probes that were complementary to overlapping sequences starting at the 3′ end. The results provided strong evidence that endonuclease cleavage in the body of the message, rather than degradation from the native 3′ end, is the rate-determining step for mRNA decay.

Abstract:
The instability of messenger RNA is crucial to the control of gene expression. In Bacillus subtilis, RNase Y is the major decay-initiating endoribonuclease. Here, we show how this key enzyme regulates its own synthesis by modulating the longevity of its mRNA. Autoregulation is achieved through cleavages in two regions of the rny (RNase Y) transcript: (i) within the first ~100 nucleotides of the open reading frame, immediately inactivating the mRNA for further rounds of translation; (ii) cleavages in the rny 5′ UTR, primarily within the 5′-terminal 50 nucleotides, creating entry sites for the 5

Abstract:
RNA degrading enzymes and multi-enzyme complexes govern a variety of cellular processes. The role of these enzymes and multi-enzyme assemblies has been suggested to govern gene expression levels in bacteria with modulations leading to a so-called phenotypic switch from the persistent (biofilm forming) to a virulent phase. The role of these enzymes in modulating RNA-dependent signal transduction is less understood although several studies implicate these enzymes in regulating the intracellular levels of RNA messengers. Given the multi-functional roles of these enzymes from housekeeping fu
