Elimination of Ribosome Inactivating Factors Improves the Efficiency of Bacillus subtilis and Saccharomyces cerevisiae Cell-Free Translation Systems

Frontiers in Microbiology, 2018
Cell-free translation systems based on cellular lysates optimized for in vitro protein synthesis have multiple applications both in basic and applied science, ranging from studies of translational regulation to cell-free production of proteins and ...

Charged and hydrophobic surfaces on the a chain of shiga-like toxin 1 recognize the C-terminal domain of ribosomal stalk proteins. [PDF]

PLoS ONE, 2012
Shiga-like toxins are ribosome-inactivating proteins (RIP) produced by pathogenic E. coli strains that are responsible for hemorrhagic colitis and hemolytic uremic syndrome.

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Differential up‐regulation by tRNAs of ribosome‐inactivating proteins [PDF]

FEBS Letters, 1995
Some plant ribosome‐inactivating proteins (RIPs) with RNA‐N‐glycosidase activity on 28S RNA require, for the inactivation of ribosomes, the presence of macromolecular cofactors present in post‐ribosomal supernatants. In the case of gelonin one of the cofactors is tRNATrp lacking one or two nucleotides at the 3′‐CCA end [Brigotti, M., Carnicelli, D ...

TM9SF2 Maintains Golgi Integrity and Regulates Ricin-Induced Cytotoxicity

Toxins
TM9SF2 belongs to a family of highly conserved nonaspanin proteins, and has been frequently identified as one of the important host factors for a plethora of lethal pathogens and toxins in previous genome-wide screening studies.

Structural Basis of Shiga Toxin Neutralization by Human Antibodies Targeting Canonical Receptor‐Binding and Non‐Canonical Assembly Sites

Advanced Science, EarlyView.
Cryo‐electron microscopy structures reveal two distinct neutralization mechanisms of fully human monoclonal antibodies targeting the Shiga toxin 1a B subunit. RDS059 occludes the Gb3 receptor‐binding site, whereas RDS045 engages a lateral quaternary epitope to disrupt holotoxin assembly.

Identification of the prebiotic translation apparatus within the contemporary ribosome [PDF]

, 2009
A structural element that could have existed independently in the prebiotic era was identified at the active site of the contemporary ribosome. It is suggested to have functioned as a proto-ribosome catalyzing peptide bond formation and non-coded ...

An N-Terminal Fragment of Yeast Ribosomal Protein L3 Inhibits the Cytotoxicity of Pokeweed Antiviral Protein in Saccharomyces cerevisiae

Toxins, 2014
We have previously shown that ribosomal protein L3 is required for pokeweed antiviral protein (PAP), a type I ribosome inactivating protein, to bind to ribosomes and depurinate the α-sarcin/ricin loop (SRL) in yeast.

Single‐Molecule Imaging of Endogenous RNA Using a Miniaturized and Circularly Permuted CRISPR‐Cas13 Degron‐Masking System CDegSR

Advanced Science, EarlyView.
CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.
