S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

The conserved XPF:ERCC1-like Zip2:Spo16 complex controls meiotic crossover formation through structure-specific DNA binding. [PDF]

, 2019
In eukaryotic meiosis, generation of haploid gametes depends on the formation of inter-homolog crossovers, which enable the pairing, physical linkage, and eventual segregation of homologs in the meiosis I division.

Crystallization and preliminary crystallographic analysis of the DNA gyrase B protein from B-stearothermophilus [PDF]

, 1996
DNA gyrase B (GyrB) from B. stearothermophilus has been crystallized in the presence of the non-hydrolyzable ATP analogue, 5'-adenylpl-beta-gamma-imidodiphosphate (ADPNP), by the dialysis method.

Regulated Cell Death in Idiopathic Pulmonary Fibrosis

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
This graphical abstract illustrates regulated cell death (RCD) across key pulmonary cell types—including alveolar epithelial cells, fibroblasts, macrophages, and endothelial cells—modulated through a dynamic death modulation network within the IPF microenvironment.

Crystallization and preliminary X-ray analysis of neoagarobiose hydrolase from Saccharophagus degradans 2-40 [PDF]

, 2009
Many agarolytic bacteria degrade agar polysaccharide into the disaccharide unit neoagarobiose [O-3,6-anhydro-α-L-galactopyranosyl-(1→3)-D-galactose] using various β-agarases.

Radiation damage in sub‐Ångström resolution macromolecular crystallography: a low‐dose study

Acta Crystallographica Section D, Volume 82, Issue 5, Page 484-491, May 2026.
This first systematic radiation‐damage study at 0.55 Å resolution reveals extensive small conformational changes in response to dose. The findings demonstrate the benefits of using large crystals fully bathed in a large `top‐hat' beam with a uniform fluence profile, together with low‐dose data‐collection protocols, for sub‐Ångström structure ...

An atlas of plant selenium metabolism

New Phytologist, Volume 250, Issue 4, Page 2041-2060, May 2026.
Summary Selenium (Se) is not only a rare and toxic element but also an essential micronutrient for humans and animals that is often in short supply. Terrestrial plants do not require Se, but it can have growth‐promoting or negative effects, depending on the exposure level.

Dietary Organic Selenium Supplementation for Weaned Piglets Challenged with Deoxynivalenol

Animals
This study aimed to investigate the effects of dietary selenium (Se) supplementation levels on the apparent total tract digestibility (ATTD) of crude protein, crude fat, and crude ash, and cecal microbiota diversity and composition in nursery piglets ...

Selenoprotein H Functions as a PPARα Coactivator to Link Selenium Homeostasis to Hepatic Lipid Metabolism and Protect against Steatohepatitis

Advanced Science, Volume 13, Issue 22, 17 April 2026.
Our study identifies selenium deficiency as a hallmark of MASH pathogenesis. Dietary selenium supplementation enhances hepatic fatty acid oxidation (FAO) and attenuates MASH progression by activating the PPARα pathway via selenoprotein H (SELENOH). This selenium‐SELENOH‐PPARα nexus redefines the functional scope of selenoproteins, moving from redox ...
