Rhabdopeptides are synthesized by non-ribosomal peptide synthetases (NRPSs) and the multiple NRPS subunits interact through docking domains (DD). Here the authors provide insights into DD interaction patterns and present the structures of three N-terminal docking domains (NDD) and a NDD-CDD complex and derive a set of recognition rules for DD interactions.
The growth-promoting activity of mTORC1 is regulated by amino acid availability via the Rag GTPases. Here, the authors demonstrate Src-dependent control of cell size and autophagy through disruption of the Rag GTPase–GATOR1 complex and mTORC1 activation at the lysosomal surface.
The early molecular events that ultimately lead to neuronal cell death in pathologies such as Parkinson’s disease are poorly understood. Here the authors use pluripotent stem-cell-derived human midbrain neurons and chemical biology tools to gain molecular level insight into the events induced by toxic and genetic stresses that mimic those occurring during neurodegeneration.
In the ventral basal ganglia circuit, the ventral pallidum (VP) receives major inputs from the nucleus accumbens (NAc) and is involved in reward processing. Here, the authors report that, contrary to the accepted model, signals related to the relative value of reward in VP emerge before NAc and are more robust.
Gels filtering particles by interactions are a goal of nanotechnology; this is difficult when particles are larger than the mesh of the gel. Here, the authors present an equilibrium mechanism where binding dynamics of crosslinks are affected by interacting particles so that particles experience enhanced diffusion.
Oncolytic virotherapy is a promising strategy for cancer treatment. In this study, the authors demonstrate that DNA-dependent protein kinase (DNA-PK) inhibition sensitizes cancer cells to M1 virus and improves therapeutic effects in refractory cancer models in vivo and in patient tumour samples.
Interactions between metal nanoparticles (NPs) and metal–organic frameworks (MOFs) in their composite forms have proven to exhibit beneficial properties. Here the authors present a unique approach to immobilise Pd NPs and, more importantly, to generate tunable basic sites within an anionic defective MOF.
Specific types of inhibitory neurons exhibit prolonged, high-frequency barrages of action potentials. Here, the authors show that astrocytes might mediate such barrage firing.
Current digital coding metasurfaces are only space-encoded. Here, the authors propose space-time modulated digital coding metasurfaces to obtain simultaneous manipulations of electromagnetic waves and present harmonic beam steering, beam shaping, and scattering-signature control as application examples.
The FtsZ protein assembles into a structure known as ‘Z-ring’ at midcell for bacterial cell division. Here, Söderström et al. show that Z-ring assembly and dynamics in E. coli cells with unnatural shapes, such as squares and hearts, are generally similar to those observed in cells with normal shape.
Ischemic reperfusion or nutrient deprivation that produces reactive oxygen species can lead to a loss of muscle contractile function. Here the authors show that glutathionylation of the lysine methyltransferase SMYD2 contributes to degradation or disassembly of sarcomeres.
Interfering RNA have a range of therapeutic and research based applications, issues with delivery have made systems that make siRNA in situ of interest. Here, the author report on the creation of a DNA hydrogel with improved stability and transcription efficiency over plasmid DNA.
It is challenging to design photosensitizers (PS) with high quantum yields generating singlet oxygen due to severe aggregation between the hydrophobic PSs. Here they develop organoplatinum(II) metallatocage-based PS to overcome these challenges and show excellent antitumor effect.
Exciton diffusion length and directionality are important parameters in artificial photosynthetic devices. Here, the authors present a way to make crystalline chromophore assemblies with bespoke architecture, fabricating one exhibiting anisotropic exciton transport properties.
Bounding the capacity of thermal attenuators would give a powerful instrument to describe decoherence occurring in optical fibres and free space links. Here, the authors improve on the existing upper bounds in the region of small thermal noise, which is of interest for quantum communication.
Enzymes of the six-transmembrane epithelial antigen of the prostate (STEAP) family reduce Fe3+ and Cu2+ ions to facilitate metal-ion uptake by mammalian cells. Here, authors employ single-particle cryo-EM to gain insights into the molecular principles of iron reduction by human STEAP4 .
The decision when to stop an intervention is a critical component of parasite elimination programmes, but reliance on surveillance data alone can be inaccurate. Here, Michael et al. combine parasite transmission model predictions with disease survey data to more reliably determine when interventions can be stopped.
The halictid bee Lasioglossum albipes has both solitary and eusocial individuals, making it a model for social evolution. Here, Kocher et al. identify a genetic variation associated with this social polymorphism, including a variant that can regulate the expression of an autism-associated gene, syntaxin 1a.
The emergence of superconductivity from the normal state in the cuprates above the transition temperature (Tc) has been controversial. Here, Pelc et al. report nonlinear conductivity, resulting from superconducting precursors only, vanishing exponentially above Tc both with temperature and with magnetic field.
To prevent ligand-independent dimerisation the epidermal growth factor receptor (EGFR) is autoinhibited by an extracellular dimer interaction. Here, the authors use several imaging technologies and simulations to provide structural insights on the inactive species and on how intracellular mutations circumvent the autoinhibition of the basal state.
