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
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]
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.

Critical roles for ‘housekeeping’ nucleases in type III CRISPR-Cas immunity
CRISPR-Cas systems are a family of adaptive immune systems that use small CRISPR RNAs (crRNAs) and CRISPR-associated (Cas) nucleases to protect prokaryotes from invading plasmids and viruses (i.e., phages).

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability [PDF]
Significance R loops form during transcription when the mRNA hybridizes back to the template DNA forming a stable DNA–RNA hybrid. Stable R loops can block replication and transcription machineries, leading to genome instability and human diseases.

Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures.

Human RNase H1 is associated with protein P32 and is involved in mitochondrial pre-rRNA processing. [PDF]
Mammalian RNase H1 has been implicated in mitochondrial DNA replication and RNA processing and is required for embryonic development. We identified the mitochondrial protein P32 that binds specifically to human RNase H1, but not human RNase H2. P32 binds

SR7 – a dual-function antisense RNA from Bacillus subtilis
Here, we describe SR7, a dual-function antisense RNA encoded on the Bacillus subtilis chromosome. This RNA was earlier described as SigB-dependent regulatory RNA S1136 and reported to reduce the amount of the small ribosomal subunit under ethanol stress.

Characterization of Components of the Staphylococcus aureus mRNA Degradosome Holoenzyme-Like Complex [PDF]
ABSTRACTBacterial two-hybrid analysis identified theStaphylococcus aureusRNA degradosome-like complex to include RNase J1, RNase J2, RNase Y, polynucleotide phosphorylase (PNPase), enolase, phosphofructokinase, and a DEAD box RNA helicase. Results also revealed that the recently recognized RNase RnpA interacts with theS. aureusdegradosome and that this
