Recent technological advances have deepened our perception of cellular structure. However, most structural data doesn't originate from intact cells, limiting our understanding of cellular processes. Here, we discuss current and future developments that will bring us towards a structural picture of the cell. Electron cryotomography is the standard bearer, with its ability to provide in cellulo snapshots. Single-particle electron microscopy (of purified biomolecules and of complex mixtures) and covalent crosslinking combined with mass spectrometry also have significant roles to play, as do artificial intelligence algorithms in their many guises. To integrate these multiple approaches, data curation and standardisation will be critical - as is the need to expand efforts beyond our current protein-centric view to the other (macro)molecules that sustain life.

Defects significantly influence charge transport in CHNHPbI (MAPbI) perovskite solar cells, particularly at interfaces. Using quantum dynamics simulation, we reveal a distinct interstitial iodine (I) defect behavior at different positions in the TiO/MAPbI system. In the perovskite bulk-like region, I exhibits high mobility and dissociates detrimental iodine trimers, facilitating small-to-large polaron transition and promoting shallow trap formation.

Coarse-grained (CG) lipid models enable efficient simulations of large-scale membrane events. However, achieving both speed and atomic-level accuracy remains challenging. Graph neural networks (GNNs) trained on all-atom (AA) simulations can serve as CG force fields, which have demonstrated success in CG simulations of proteins.

Membrane-protein quality control in Escherichia coli involves coordinated actions of the AAA+ protease FtsH, the insertase YidC and the regulatory complex HflKC. These systems maintain proteostasis by facilitating membrane-protein insertion, folding and degradation. To gain structural insights into a putative complex formed by FtsH and YidC, we performed single-particle cryogenic electron microscopy on detergent-solubilized membrane samples, from which FtsH and YidC were purified using Ni-NTA affinity and size-exclusion chromatography.

Covering: up to April 2025Bacterial aromatic polyketides represent a notable class of natural products that have found extensive applications in clinical treatments. In their biosynthesis, oxidative rearrangements represent critical transformations that typically afford diverse scaffolds, structural rigidity, and biological activities. In this context, it is evident that redox enzymes are frequently implicated in various rearrangement processes, whereby they facilitate the transformation of pathway precursors into mature natural products.
