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.

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Bio‐active designed peptide for hair keratin strengthening

International Journal of Cosmetic Science, EarlyView.
Bioactive tripeptides through in silico screening revealed KCV (Tripeptide‐132) as the most promising keratin‐targeting candidate. Experimental studies confirmed its superior hair‐strengthening performance with 44% tensile strength enhancement, 50% breakage reduction, improved surface integrity and fibre penetration.

Targeted keratin repair: A plant‐based approach to hair strength and surface restoration

International Journal of Cosmetic Science, EarlyView.
Application of Avena strigosa seed extract may reinforce keratin bonding, restoring hair fibre integrity by promoting intramolecular interactions at damaged sites of keratin proteins. Abstract Objective Chemical and thermal stress disrupts the intramolecular and intermolecular interactions that stabilize hair keratin, leading to structural degradation ...

Protein hydrolysates from Italian sea bream and sea bass aquaculture side streams – chemical, biological, and techno-functional characterization

Frontiers in Marine Science
With the increasing demand for food and sustainable food processes, using side streams from food production has gained increased attention. After fish filleting, a significant amount of the biomass, such as heads, viscera, backbones, and skins, is left ...

Evaluating 20% and 40% Inclusion of Sugary Former Foods in Pig Diets: Effects on Growth Performance, Feeding Behaviour, Carcass and Meat Quality Traits

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Former food products (FFP) are food industry leftovers that can be used as feed ingredients. We investigated the effects of sugary FFP on growth, feeding behaviour, carcass and meat quality of pigs fattened to a heavy weight. Three inclusion levels were tested: 0% (FFP‐0 = control), 20% (FFP‐20) and 40% (FFP‐40) FFP in grower (20–60 kg BW ...

A Nutrient‐Responsive LuxR Regulator Orchestrates Effector Gene Expression Across the Legionella Genus

Molecular Microbiology, EarlyView.
LexR1 is a LuxR‐type regulator that links nutrient sensing to effector gene expression in Legionella. Activated by a casamino acid‐derived ligand, LexR1 directly controls multiple effector genes using a conserved regulatory element present in numerous putative effectors across different Legionella species.
