A high-resolution structure of carboxyspermidine decarboxylase, a member of the PLP-dependent β/α-barrel-fold decarboxylase family, is analyzed.

High-resolution X-ray and neutron crystallography reveal redox-dependent rearrangements in the hydrogen-bond network of ferredoxin–NADP⁺ reductase (FNR), highlighting structural changes around the FAD cofactor and shifts in water molecules that underpin its electron-transfer mechanism. These findings provide valuable insights into the functional modulation of FNR.

A versatile construct was designed to improve the purification yield and facilitate structural studies of the ligand-binding domain of the pregnane X receptor.

The first structural analysis of a nucleic acid using crystals obtained under microgravity crystallization in space is reported. A DNA/RNA heteroduplex was successfully crystallized in a microgravity environment, improving the size and appearance of the crystals compared with crystals obtained on Earth.

This communication describes the crystal structure of TRIM21 in complex with suramin, providing new opportunities to target this E3 ligase.

The crystal structure of dihydroorotate dehydrogenase from H. pylori bound to flavin mononucleotide was determined at 2.25 Å resolution in space group P2₁.

Single-particle cryo-EM structures of apo and atorvastation-bound human 3-hydroxy-3-methylglutaryl-coenzyme A reductase were determined using graphene oxide-coated grids.

The article by Belfon et al.[(2024), Acta Cryst. F80, 348–355] is corrected.
