Identification of how bioactive lipids bind and inhibit glycine transporters has the potential to be exploited in the development of a new class of analgesics for chronic pain.

The signaling ligand (p)ppGpp regulates the enzyme HPRT across species by binding to a novel class of conserved motif, yet its specificity is allosterically altered through evolution of enzyme oligomerization.

The rate of DNA unwinding by RecQ helicases is dramatically modulated by the DNA duplex stability in a geometry-dependent manner, providing an intrinsic mechanism for suppressing illegitimate recombination.

Heme accumulation is toxic, but deficiency of the heme transporter HRG1/SLC48A1 causes heme sequestration and crystallization into hemozoin within enlarged lysosomes of macrophages, thereby conferring heme tolerance to mammals.

DNA replication initiation proteins contain a disordered domain that impacts each stage of their function, from chromatin recruitment and initiator co-assembly to the subsequent displacement of the factors from chromatin.

The discovery of a biomolecular condensate involved in DNA replication has wide ranging implications.

ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.

Macrophages release 30-nm vesicular particles enriched in accessible cholesterol during cellular locomotion, a discovery that is likely relevant to cholesterol disposal by these cells.

Molecular details of how the iron–sulfur cluster cofactor of a bacterial global iron regulatory protein simultaneously senses iron and O₂ are revealed by mass spectrometry and spectroscopy.

Cardiac myosin converts energy from ATP into mechanical work by transitioning from a short-lived force-bearing state, to a post working stroke state before the release of inorganic phosphate.
