Designing macrocyclic disulfide-rich peptides for biotechnological applications

Designing macrocyclic disulfide-rich peptides for biotechnological applications, Published online: 16 April 2018; doi:10.1038/s41589-018-0039-y

Through molecular grafting, cyclic disulfide-rich peptides can be used as scaffolds to improve the stability, rigidity, and cellular uptake of bioactive peptides, although a number of factors should be considered when designing such grafted peptides.

FINO2 initiates ferroptosis through GPX4 inactivation and iron oxidation

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.

Super-long single-molecule tracking reveals dynamic-anchorage-induced integrin function

Super-long single-molecule tracking reveals dynamic-anchorage-induced integrin function, Published online: 02 April 2018; doi:10.1038/s41589-018-0032-5

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.

Unfolding of a ClC chloride transporter retains memory of its evolutionary history, Published online: 26 March 2018; doi:10.1038/s41589-018-0025-4

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.
