Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

open access: yesPlant, Cell &Environment, Volume 49, Issue 12, Page 10283-10300, December 2026.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Fragment Coverage: Unified Visualization and Quantitative Assessment of MS/MS Fragmentation Supports Metabolite Identification in Macromolecule Drug Metabolism Studies

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 21, 15 November 2026.
ABSTRACT Rationale Peptides and oligonucleotides are increasingly used as therapeutic agents, making the identification and structural elucidation of their metabolites a critical step in drug development. Liquid chromatography–mass spectrometry (LC‐MS/MS) is the primary analytical technique for this purpose; however, extensive backbone fragmentation ...

Integration of Chemical Probes and Degradomics Reveals That Cathepsin B Functions Primarily as a Dipeptidyl Carboxypeptidase in Macrophages

open access: yesChemMedChem, Volume 21, Issue 21, 12 November 2026.
An integrated chemical biology and degradomics approach reveals the proteolytic landscape of cathepsin B in mouse macrophages. Z‐RK‐AOMK perturbs the cysteine cathepsin network and reveals that cathepsin B predominantly exhibits dipeptidyl carboxypeptidase activity in cells.

Synthesis of a Dipeptide and Testing for Antimicrobial Activity

open access: yes
This project will involve the production of a dipeptide using two amino acids. Both amino acids will be protected and a coupling reagent will be used to join these two peptides together in attempt to prevent unnecessary acid base reactions from happening,

Contribution of UbrA, a ubiquitin ligase essential for Arg/N-degron pathway, to peptidase gene expression in Aspergillus oryzae

open access: yesApplied and Environmental Microbiology
The degradation of intracellular proteins by N-degron pathways depends on their N-terminal amino acids. In budding yeast, the Arg/N-degron pathway controls the expression of dipeptide/tripeptide transporter gene by degrading a transcriptional repressor ...

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, Volume 20, Issue 11, Page 2584-2610, November 2026.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...
