Phylogenetic identification of bacterial MazF toxin protein motifs among probiotic strains and foodborne pathogens and potential implications of engineered probiotic intervention in food [PDF]
, 2012 BACKGROUND: Toxin-antitoxin (TA) systems are commonly found in bacteria and Archaea, and it is the most common mechanism involved in bacterial programmed cell death or apoptosis. Recently, MazF, the toxin component of the toxin-antitoxin module, has been

Pressure-dependent 13C chemical shifts in proteins: Origins and applications [PDF]
, 2009 Pressure-dependent (13)C chemical shifts have been measured for aliphatic carbons in barnase and Protein G. Up to 200 MPa (2 kbar), most shift changes are linear, demonstrating pressure-independent compressibilities.

The role of ribonucleases in regulating global mRNA levels in the model organism Thermus thermophilus HB8 [PDF]
, 2014 BACKGROUND: RNA metabolism, including RNA synthesis and RNA degradation, is one of the most conserved biological systems and has been intensively studied; however, the degradation network of ribonucleases (RNases) and RNA substrates is not fully ...

Molecular mechanisms of CRISPR-mediated microbial immunity [PDF]
, 2013 Bacteriophages (phages) infect bacteria in order to replicate and burst out of the host, killing the cell, when reproduction is completed. Thus, from a bacterial perspective, phages pose a persistent lethal threat to bacterial populations.

Viruses and the cellular RNA decay machinery. [PDF]
, 2010 The ability to control cellular and viral gene expression, either globally or selectively, is central to a successful viral infection, and it is also crucial for the host to respond and eradicate pathogens.

Frontiers in Microbiology, 2016 Persistence is a transient and non-inheritable tolerance to antibiotics by a small fraction of a bacterial population. One of the proposed determinants of bacterial persistence is toxin-antitoxin systems (TAS) which are also implicated in a wide range of

Intramyocardial gene silencing by interfering RNA [PDF]
, 2017 RNAi is a widely used methodology for gene silencing. The action mechanism of siRNA molecules has been well studiedin recent years, and the technique has been optimized in terms of safety and effectiveness. Cardiovascular diseases havea high incidence in

The RasGAP-associated endoribonuclease G3BP assembles stress granules.
The Journal of cell biology, 2003 Stress granules (SGs) are formed in the cytoplasm in response to various toxic agents, and are believed to play a critical role in the regulation of mRNA metabolism during stress. In SGs, mRNAs are stored in an abortive translation initiation complex that can be routed to either translation initiation or degradation.

Subcellular partitioning of MRP RNA assessed by ultrastructural and biochemical analysis. [PDF]
, 1994 A small RNA encoded within the nucleus is an essential subunit of a RNA processing endonuclease (RNase MRP) hypothesized to generate primers for mitochondrial DNA replication from the heavy strand origin of replication.
