RNase P Branches Out from RNP to Protein: Organelle-Triggered Diversification? [PDF]

, 2012
RNase P is the enzyme that removes 5′ leader sequences from precursor tRNAs. Remarkably, in most organisms, RNase P is a ribonucleoprotein particle where the RNA component is responsible for catalysis. In this issue of Genes \u26 Development, Gutmann and

Yersiniae Virulence Factors: Type III Secretion System [PDF]

, 2008
Several Gram-negative pathogenic bacteria have evolved a complex protein secretion system termed the Type Three Secretion System (TTSS) to deliver bacterial effector proteins into host-cells that then modulate host-cellular functions.

Structure and function of Campylobacter jejuni polynucleotide phosphorylase (PNPase): Insights into the role of this RNase in pathogenicity

Biochimie
Ribonucleases are in charge of the processing, degradation and quality control of all cellular transcripts, which makes them crucial factors in RNA regulation. This post-transcriptional regulation allows bacteria to promptly react to different stress conditions and growth phase transitions, and also to produce the required virulence factors in ...

A bacterial secreted translocator hijacks riboregulators to control type III secretion in response to host cell contact.

PLoS Pathogens, 2019
Numerous Gram-negative pathogens use a Type III Secretion System (T3SS) to promote virulence by injecting effector proteins into targeted host cells, which subvert host cell processes.

An analytic approximation of the feasible space of metabolic networks

, 2017
Assuming a steady-state condition within a cell, metabolic fluxes satisfy an under-determined linear system of stoichiometric equations. Characterizing the space of fluxes that satisfy such equations along with given bounds (and possibly additional ...

Structural Insights into the Rrp4 Subunit from the Crystal Structure of the Thermoplasma acidophilum Exosome

Biomolecules
The exosome multiprotein complex plays a critical role in RNA processing and degradation. This system governs the regulation of mRNA quality, degradation in the cytoplasm, the processing of short noncoding RNA, and the breakdown of RNA fragments.
