The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Site-specific and time-dependent activation of the endocannabinoid system after transection of long-range projections [PDF]
Background: After focal neuronal injury the endocannabinioid system becomes activated and protects or harms neurons depending on cannabinoid derivates and receptor subtypes.

We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

IKKα regulation of canonical NF-κB activation downstream of Nod1-mediated peptidoglycan recognition : "and" Endocytosis-independent function of clathrin heavy chain in the control of basal NF-κB activation [PDF]
NF-κB is a transcription factor involved in the regulation of inflammation and innate immunity. The IκB kinase (IKK) complex contains two catalytic subunits, IKKα and IKKβ, and plays an essential role in the activation of NF-κB through the ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Activation Energy of Enzyme and Non-Enzyme Catalyzed Reactions
The goal of this research was to compare the activation energy and rate constants of an enzyme catalyzed and a non-enzyme catalyzed hydrolysis reaction at different temperatures.

Angiotensin-converting enzyme I/D polymorphism and preeclampsia risk: Evidence of small-study bias [PDF]
Background Inappropriate activation of the renin-angiotensin system may play a part in the development of preeclampsia. An insertion/deletion polymorphism within the angiotensin-I converting enzyme gene (ACE-I/D) has shown to be reliably associated with ...

Calpain small subunit homodimerization is robust and calcium‐independent
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
