RNA components of Escherichia coli degradosome: Evidence for rRNA decay [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Recently, we found that a multicomponent ribonucleolytic degradosome complex formed around RNase E, a key mRNA-degrading and 9S RNA-processing enzyme, contains RNA in addition to its protein components. Herein we show that the RNA found in the degradosome consists primarily of rRNA fragments that have a range of distinctive sizes.

Adjacent single-stranded regions mediate processing of tRNA precursors by RNase E direct entry [PDF]

open access: yes, 2014
The RNase E family is renowned for being central to the processing and decay of all types of RNA in many species of bacteria, as well as providing the first examples of endonucleases that can recognize 50 -monophosphorylated ends thereby increasing

Editosome Accessory Factors KREPB9 and KREPB10 in Trypanosoma brucei [PDF]

open access: yes, 2012
Multiprotein complexes, called editosomes, catalyze the uridine insertion and deletion RNA editing that forms translatable mitochondrial mRNAs in kinetoplastid parasites.

A eukaryotic-like 3′ untranslated region in Salmonella enterica hilD mRNA [PDF]

open access: yes, 2014
Long 3' untranslated regions (3'UTRs) are common in eukaryotic mRNAs. In contrast, long 3'UTRs are rare in bacteria, and have not been characterized in detail.

Structural insights into RNase J that plays an essential role in Mycobacterium tuberculosis RNA metabolism

open access: yesNature Communications, 2023
Ribonucleases (RNases) are responsible for RNA metabolism. RNase J, the core enzyme of the RNA degradosome, plays an essential role in global mRNA decay.

Allosteric activation of RhlB by RNase E induces partial duplex opening in substrate RNA

open access: yesFrontiers in Molecular Biosciences, 2023
The E. coli DEAD-Box helicase RhlB is responsible for ATP-dependent unwinding of structured mRNA to facilitate RNA degradation by the protein complex degradosome.

Examining the Protein Interactome and Subcellular Localization of RNase J2 Complexes in Streptococcus mutans

open access: yesFrontiers in Microbiology, 2019
Regulated RNA turnover is vital for the control of gene expression in all cellular life. In Escherichia coli, this process is largely controlled by a stable degradosome complex containing RNase E and a variety of additional enzymes.

Structural Insights into the Dimeric Form of Bacillus subtilis RNase Y Using NMR and AlphaFold

open access: yesBiomolecules, 2022
RNase Y is a crucial component of genetic translation, acting as the key enzyme initiating mRNA decay in many Gram-positive bacteria. The N-terminal domain of Bacillus subtilis RNase Y (Nter-BsRNaseY) is thought to interact with various protein partners ...

Genes important for catalase activity in Enterococcus faecalis. [PDF]

open access: yesPLoS ONE, 2012
Little in general is known about how heme proteins are assembled from their constituents in cells. The Gram-positive bacterium Enterococcus faecalis cannot synthesize heme and does not depend on it for growth.
