Enzyme as Maxwell's Demon: Steady-state Deviation from Chemical Equilibrium by Enhanced Enzyme Diffusion [PDF]

arXiv
Enhanced enzyme diffusion (EED), in which the diffusion coefficient of an enzyme transiently increases during catalysis, has been extensively reported experimentally. We numerically and analytically demonstrate that such enzymes can act as Maxwell's demons.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Aerobic exercise improves astrocyte mitochondrial quality and transfer to neurons in a mouse model of Alzheimer's disease

Brain Pathology, Volume 35, Issue 3, May 2025.
Aerobic exercise improves transfer of healthy mitochondria from astrocytes to neurons in the 5 × FAD mice. Abstract Mitochondrial dysfunction is a well‐established hallmark of Alzheimer's disease (AD). Despite recent documentation of transcellular mitochondrial transfer, its role in the pathogenesis of AD remains unclear.

Ergosterol‐induced immune response in barley involves phosphorylation of phosphatidylinositol phosphate metabolic enzymes and activation of diterpene biosynthesis

New Phytologist, Volume 246, Issue 3, Page 1236-1255, May 2025.
Summary Lipids play crucial roles in plant–microbe interactions, functioning as structural components, signaling molecules, and microbe‐associated molecular patterns (MAMPs). However, the mechanisms underlying lipid perception and signaling in plants remain largely unknown. Here, we investigate the immune responses activated in barley (Hordeum vulgare)

ReactZyme: A Benchmark for Enzyme-Reaction Prediction [PDF]

38th Conference on Neural Information Processing Systems (NeurIPS 2024) Track on Datasets and Benchmarks
Enzymes, with their specific catalyzed reactions, are necessary for all aspects of life, enabling diverse biological processes and adaptations. Predicting enzyme functions is essential for understanding biological pathways, guiding drug development, enhancing bioproduct yields, and facilitating evolutionary studies. Addressing the inherent complexities,

Axial Ligand Lability and Coordination Induced Spin State Variations of Tetracarbene Iron(II) Thiolato Complexes

European Journal of Inorganic Chemistry, Volume 28, Issue 11, April 9, 2025.
A series of newly synthesized iron(II) thiolato complexes based on two different macrocyclic tetracarbene ligands shows coordination induced spin state variations from low‐spin to intermediate spin states as well as ligand lability leading to a temperature‐dependent equilibrium between the penta‐ and six‐coordinate species and axial ligand scrambling ...

Multidimensional Engineering of Escherichia coli for Efficient Adipic Acid Synthesis From Cyclohexane

Advanced Science, Volume 12, Issue 14, April 10, 2025.
An engineered Escherichia coli is developed to efficiently produce adipic acid (AA) from cyclohexanol, KA oil (a mixture of cyclohexanol and cyclohexanone), or cyclohexane through a combination of enzyme screening, protein fusion, and genome editing techniques. This approach has achieved the highest recorded productivity for biological AA production to
