Engineering transfer RNAs to read codons consisting of four bases requires changes in tRNA that go beyond the anticodon sequence.

The redox reagent dithiothreitol causes toxicity by depleting S-adenosylmethionine levels, and dietary vitamin B12 could alleviate this toxicity via the methionine synthase enzyme.

Deciphering the mechanism of action of a large family of natural and synthetic cytotoxic lipids bioactivated by enantiospecific oxidation into protein-reactive species inspires the development of enzyme-specific prodrugs.

Single particle cryo-electron microscopy associated with functional studies reveal a critical role of N- and C-terminal tails in the autoinhibition of the disease-related ATP8B1-CDC50A lipid flippase, the possible role of phosphorylation in autoinhibition relief, and strong activation by PI(3,4,5)P₃.

Poly(ADP-ribose) (PAR) Trackers (PAR-Ts) are optimized PAR sensors that allow the detection and quantification of PAR levels in extracts, living cells, and living tissues with high sensitivity, and with temporal and spatial precision, in many different experimental and biological systems.

A novel mechanism of intramembrane protease regulation involves a protein blocking the active site of the enzyme.

Spermidine-mediated superoxide generation affects iron homeostasis in Escherichia coli.

The proteasomal deubiquitinase UCHL5/UCH37 uses a face distinct from the canonical ubiquitin binding site to engage K48-linked ubiquitin chains and catalyze chain debranching.

Development, validation, and use of an effector membrane translocation biosensor platform reveals G protein coupling selectivity signatures for 100 GPCRs that range from remarkable selectivity to full promiscuity toward the different G protein subtypes.

Multiple cryo-electron microscopy structures of a plant ABC transporter exporting glutathione derivatives captured a closed conformation proposed to enforce the export directionality, while a complex central to the coupling mechanism containing both glutathione and closed nucleotide binding domains remains elusive.
