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

open access: yesThe 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.

Effect of selenium hyperaccumulation on the root endophytic and rhizosphere microbiome of two Astragalus species

open access: yesPlant Biology, Volume 28, Issue 6, Page 1960-1972, October 2026.
Selenium hyperaccumulation has little impact on the overall microbiome diversity but rather affects interactions with key plant microbial mutualists, including rhizobia. Abstract Metal hyperaccumulation is prevalent throughout plant evolution, particularly in the legume family (Fabaceae), and acts as a presumed chemical defence against herbivory ...

Paeonol Alleviate Cisplatin‐ and Noise‐Induced Hearing Loss by Preserving Hair Cell Ribosome Biogenesis

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Paeonol protects against cisplatin‐ and noise‐induced hearing loss by mitigating oxidative damage and preserving protein homeostasis in cochlear hair cells, revealing a novel mechanism involving ribosome biogenesis. ABSTRACT Background Hearing loss primarily results from irreversible cochlear hair cell (HC) damage caused by factors such as noise, aging,

Dietary Organic Selenium Supplementation for Weaned Piglets Challenged with Deoxynivalenol

open access: yesAnimals
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 ...

Biofortification of Chlorella vulgaris With Selenium and Iron Microminerals and Investigation of Some Bioactive Compounds: A Promising Dietary Supplement

open access: yesFood Science &Nutrition, Volume 14, Issue 9, September 2026.
This study was designed to investigate the effects of varying concentrations of selenium and iron on the growth of Chlorella vulgaris microalgae and its potential for bioaccumulation of these essential micronutrients. The optimal concentration for each metal was determined through detailed assessment of growth parameters.

Mitochondria as the Hub of Apoptosis: A Comprehensive Insight From Mitochondria to Interactions With Other Organelles

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Mitochondria is the hub of apoptosis in various diseases. The disruption of mitochondrial structure (including membrane rupture, cristae remodeling, and mitochondrial membrane lipid redistribution), the imbalance of mitochondrial dynamics (including fusion and fission, autophagy), the release, disruption, and mutation of mitochondria DNA, as well as ...

AVIDbase: A biologically accurate structural dataset of nanobody‐antigen complexes

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Accurate structural data in a standardized format is one of the key factors behind the success of machine learning (ML)‐based methods for protein design and structure prediction. However, their application to nanobody‐antigen complexes has lower success rates compared to globular protein complexes, partly due to the limited amount of high ...

Selenomethionine as substrate for glutamine transaminase.

open access: yes, 1994
Selenomethionine is as a good substrate as methionine for bovine liver glutamine transaminase (E.C. 2.6.1.15). Almost identical Km values for methionine, selenomethionine, 4-methylthio-2-oxobutanoic acid and 4-methylseleno-2-oxobutanoic acid have been ...

Biological Chemistry of Hydrogen Selenide

open access: yesAntioxidants, 2016
There are no two main-group elements that exhibit more similar physical and chemical properties than sulfur and selenium. Nonetheless, Nature has deemed both essential for life and has found a way to exploit the subtle unique properties of selenium to ...
