Organ‐Specific Phytochemical Composition and Bioactivity Profiling of Chaerophyllum aksekiense: A Multiassay Antioxidant, Enzyme Inhibition, and Correlation‐Based Evaluation

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
This study reveals the organ‐specific phytochemical specialization of the endemic Chaerophyllum aksekiense for the first time. Although leaves exhibit the highest phenolic content and antioxidant capacity, flowers stand out with flavonoid accumulation, and roots demonstrate potent enzyme inhibition.

Positional scanning and computational modeling reveal determinants of legumain transpeptidase activity

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Legumain is a lysosomal cysteine protease that plays a central role in antigen processing for MHC class II presentation. Beyond its canonical proteolytic activity, legumain can also function as a peptide ligase or transpeptidase. This non‐canonical activity becomes particularly relevant under pathophysiological conditions such as cancer and ...

Substrate selectivity of human histidine methyltransferase METTL9

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Methylation of histidine residues in zinc transporters by histidine methyltransferase METTL9 plays an important role in modulating their metal‐binding properties. Here, we report synthetic, enzymatic, and computational studies on human METTL9‐catalyzed Nπ‐methylation of His375 in zinc transporter SLC39A5‐derived peptides in which the histidine

A Mass Spectrometric Approach: VOC Emissions, Fatty Acid Profile, and Bacteriota Identification of Spider Communities

open access: yesChemistrySelect, Volume 11, Issue 17, 5 May 2026.
ABSTRACT This study presents the first integrated analysis of volatile organic compounds (VOCs), fatty acids, and cultivable bacteriota in whole‐body spider specimens, combining HS‐SPME‐GC/MS, GC/MS, and MALDI‐TOF‐MS. A total of 100 spiders from five synanthropic species, Steatoda opiliones, S. bipunctata, S.

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...
