FEBS Letters, EarlyView.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 ...

FEBS Letters, EarlyView.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.

Linear Satisfiability Preserving Assignments
Journal of Artificial Intelligence Research, 2018 In this paper, we study several classes of satisfiability preserving assignments to the constraint satisfaction problem (CSP). In particular, we consider fixable, autark and satisfying assignments. Since it is in general NP-hard to find a nontrivial (i.e., nonempty) satisfiability preserving assignment, we introduce linear satisfiability preserving ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Linear Mappings that Preserve Potent Operators [PDF]
Proceedings of the American Mathematical Society, 1995 Summary: Let \(H\) and \(K\) be complex Hilbert spaces, while \({\mathcal B}(H)\) and \({\mathcal B}(K)\) denote the algebras of all linear bounded operators on \(H\) and \(K\), respectively. We characterize surjective linear mappings from \({\mathcal B}(H)\) onto \({\mathcal B}(K)\) that preserve potent operators in both directions.

FEBS Letters, EarlyView.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 ...

Outer preserving linear operators
Journal of Functional Analysis, 2011 The authors investigate bounded linear operators acting on the Hardy space \(H^2\) of analytic functions on the unit disc \(\mathbb{D}\) which preserve the set of \textit{shifted outer functions}. Recall that \(H^2\cong \ell^2(\mathbb{Z}_+)\), the isomorphism is given by \(\vec{a} = (a_k) \leftrightarrow f: f(z) = \sum_k a_k z^k\).

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells
FEBS Letters, EarlyView.Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.
