FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Strong products ofϰ-critical graphs [PDF]
Aequationes Mathematicae, 1993 LetG[H] be the lexicographic product and letG ⊠H be the strong product of the graphsG andH. It is proved that, ifG is aϰ-critical graph, then, for any graphH, $$\chi (G[H]) \leqslant \chi (H)(\chi (G) - 1) + \left[ {\frac{{\chi (H)}}{{\alpha (G)}}} \right ...

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 ...

A Sharp Lower Bound For The Generalized 3-Edge-Connectivity Of Strong Product Graphs
Discussiones Mathematicae Graph Theory, 2017 The generalized k-connectivity κk(G) of a graph G, mentioned by Hager in 1985, is a natural generalization of the path-version of the classical connectivity. As a natural counterpart of this concept, Li et al.

FEBS Letters, EarlyView.Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

On Strong Bounds for Trotter and Zeno Product Formulas with Bosonic Applications [PDF]
QuantumThe Trotter product formula and the quantum Zeno effect are both indispensable tools for constructing time-evolutions using experimentally feasible building blocks. In this work, we discuss assumptions under which quantitative bounds can be proven in the

Strong products of Kneser graphs
Discrete Mathematics, 1994 For a (simple, undirected) graph \(G = (V(G), E(G))\), let \(\chi(G)\) and \(\omega(G)\) denote the chromatic number and the clique number, respectively. A subgraph \(H\) of \(G\) is a retract of \(G\) iff there is an edge-preserving map \(h : V(G) \to V(H)\) with \(h(x) = x\) for all \(x \in V(H)\).

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.

The Restricted Edge-Connectivity of Strong Product Graphs
AxiomsThe restricted edge-connectivity of a connected graph G, denoted by λ′(G), if it exists, is the minimum cardinality of a set of edges whose deletion makes G disconnected, and each component has at least two vertices.
