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.

Biosynthesis of redox-active metabolites in response to iron deficiency in plants

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.

The dTAG system for immediate and target-specific protein degradation

The dTAG system for immediate and target-specific protein degradation, Published online: 26 March 2018; doi:10.1038/s41589-018-0021-8

The dTAG system pairs potent heterobifunctional degraders and extensible tagging strategies to achieve immediate and reversible degradation of divergent proteins, facilitating biological investigation and drug target validation in cells and in mice.

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.

Structural basis for backbone N-methylation by an interrupted adenylation domain

Structural basis for backbone N-methylation by an interrupted adenylation domain, Published online: 19 March 2018; doi:10.1038/s41589-018-0014-7

The crystal structure of a methyltransferase domain embedded within an interrupted adenylation domain provides insight into how a nonribosomal peptide synthetase N-methylates amino acid precursors for their incorporation into the peptide product.

Discovery of enzymes for toluene synthesis from anoxic microbial communities

Discovery of enzymes for toluene synthesis from anoxic microbial communities, Published online: 19 March 2018; doi:10.1038/s41589-018-0017-4

The source of biological toluene production in diverse anoxic microbial communities is a glycyl radical enzyme that catalyzes phenylacetate decarboxylation (PhdB), and its cognate activating radical S-adenosylmethionine enzyme (PhdA).

An optically controlled probe identifies lipid-gating fenestrations within the TRPC3 channel, Published online: 19 March 2018; doi:10.1038/s41589-018-0015-6

A photoswitchable diacylglycerol enabled a screen that found critical TRPC3 lipid-sensing residues and identified a lateral fenestration in the pore domain that allows lipids to protrude into the permeation pathway to control channel gating.
