FINO<sub>2</sub> initiates ferroptosis through GPX4 inactivation and iron oxidation, Published online: 02 April 2018; doi:10.1038/s41589-018-0031-6

FINO2 is a small molecule that requires the endoperoxide moiety and hydroxyl group to promote ferroptosis through indirect inhibition of GPX4 enzymatic function and direct oxidation of iron, resulting in increased lipid peroxidation.

Dissolved oxygen and a reducing-plus-oxidizing system suppress photobleaching and photoblinking in single-molecule tracking experiments, allowing long recordings of CD47 and integrin that showed temporary immobilization within focal adhesions.

TAGing for destruction, Published online: 26 March 2018; doi:10.1038/s41589-018-0024-5

Proteins brought to an E3 ubiquitin ligase are polyubiquitylated for rapid degradation via the proteasome. A new study developed a tag-based degradation system using heterobifunctional degradation inducers called dTAGs, which rapidly depleted FKBP12F36V-fused proteins in cultured cells and in mice.

A single-molecule forced unfolding of E. coli chloride transporter ClC-ec1 shows that the N- and C-terminal halves of the protein unfold independently, with exposed polar surfaces stabilized by membrane lipid head groups and water.

Biosynthesis of redox-active metabolites in response to iron deficiency in plants, Published online: 26 March 2018; doi:10.1038/s41589-018-0019-2

The biosynthesis and secretion of redox-active coumarins sideretin and fraxetin in Arabidopsis thaliana enables the plant to acquire iron under nutrient-limited conditions and provides a blueprint for the use of related compounds in other eudicots.
