Salmonella enterica serovar typhi limits the potency of typhoid toxin and ADP‐ribosylating toxin AB to establish a persistent infection

open access: yesFEBS Open Bio, EarlyView.
The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

Characterization and serotype distribution of Aggregatibacter actinomycetemcomitans detected in a population of periodontitis patients in Spain. [PDF]

open access: yes, 2009
Objective: To investigate the serotype distribution of Aggregatibacter actinomycetemcomitans (A. a.) and the polymorphism of the genes that codify the leukotoxin (ltx) and the operon of the cytolethal distending toxin (cdt) in periodontitis patients in ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

MARK4 enhances stress granule formation under oxidative stress and increases tau accumulation

open access: yesFEBS Open Bio, EarlyView.
MARK4 (red dots) localizes to stress granules (orange dots) and promotes their formation under oxidative stress by modulating TIA1 (blue dots). MARK4 and TIA1 synergistically increase tau (purple) accumulation, and the reduction of the TIA1 ortholog suppresses neurodegeneration in a fly model.

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Fluorination: A strategy to tune the interactions of molecules and nanoscale systems with biological matter

open access: yesFEBS Open Bio, EarlyView.
This minireview explores fluorination as a key strategy to optimize therapeutic molecules and nanocarriers. By incorporating different fluorinated motifs—from single atoms to linear and branched chains—drug delivery, cellular uptake, and colloidal stability can be improved and fine‐tuned.

Expression of cholera toxin B subunit in Saccharomyces cerevisiae [PDF]

open access: yes
Cholera toxin, secreted by Vibrio cholerae, consists of A and B subunits. Cholera toxin B subunit (CTB) is used in many scientific research. It has already been expressed in several bacterial and plant systems.
