Spatial Coordination Structure‐Driven Enzyme‐Like Selectivity in Single‐Atom Nanozymes

open access: yesAdvanced Materials, EarlyView.
Sun et al. reviews recent progress in enhancing the enzyme‐like catalytic selectivity of SAzymes through the rational design of their spatial coordination structures. They emphasize the structure‐activity relationships of various attributes of these coordination structures in promoting selective catalytic behavior, the strategic design of coordination ...

Metabolic Engineering of the 5‐Aminolevulinate Biosynthetic Pathway in E. coli Improves Efficiency of Hemoprotein‐Based Biocatalysis

open access: yesAngewandte Chemie, EarlyView.
We have engineered the heme biosynthetic pathway in E. coli to develop an efficient cofactor supplementation system for hemoproteins. Through the incorporation of the heterogeneous C4 pathway, the engineered cells significantly increase the expression levels of active holohemoproteins and enhance the efficiency of whole‐cell and lysate‐based ...

Cytochrome c Peroxidase–Cytochrome c Complexes

open access: yes, 2015
The yeast cytochrome c peroxidase (CCP)–cytochrome c (cytc) electron transfer system has been critically important in deciphering the molecular level details of protein–protein interactions and electron transfer. The crystal structure of the CCP–cytc together with a number mutagenesis, enzymological, and spectroscopic studies have provided a detailed ...

Automated Transcranial Photobiomodulation in Healthy Rats: Effects on Working Memory and Brain Markers

open access: yesAdvanced Therapeutics, EarlyView.
Transcranial photobiomodulation (PBM) enhances spatial working memory in healthy rats under both continuous and alternating stimulation protocols. At the neural level, PBM modulates cytochrome c oxidase activity, increases prefrontal and hippocampal synaptic markers, and induces region‐specific c‐Fos expression. These effects suggest improved cognitive

An Apple Susceptibility‐Related LRR Receptor‐Like Kinase MdRLKT21 Activates Plant Immunity by Hijacking a Trans‐Kingdom Fungal microRNA‐Like RNA

open access: yesAdvanced Science, EarlyView.
The apple susceptibility‐related LRR‐RLK MdRLKT21 competitively binds to fungal sRNA effectors and subsequently activates defenses by salvaging the expression of MdRLKT1 and MdRLKT2 and thereby releasing the resistance protein MdRFP1. These findings provide new insights into the molecular mechanism by which plants counteract pathogen‐secreted sRNA ...

Electron transfer between cytochrome c and cytochome c peroxidase in single crystals.

open access: yesJournal of the American Chemical Society, 2004
Cytochrome c (Cc) and cytochrome c peroxidase (CcP) form an important redox pair for understanding interprotein electron transfer (ET). Measurements of ET rates from photoexcited CcP substituted with Zn porphyrin to either yeast Fe(III)Cc or horse Fe(III)

Macrophage‐Mediated Transport of Insoluble Indirubin Induces Hepatic Injury During Intestinal Inflammation

open access: yesAdvanced Science, EarlyView.
Plant‐derived bioactive molecules with low solubility and permeability induce hepatocyte injury, though the mechanisms driving their hepatic effects remain poorly understood. This study identifies a novel transport pathway in which poorly soluble indirubin accumulates in the liver via macrophage‐mediated uptake in Peyer's patches, exacerbating hepatic ...

Oxidative and apoptotic effects of fluoxetine and its metabolite norfluoxetine in Daphnia magna

open access: yesArhiv za Higijenu Rada i Toksikologiju, 2020
The aim of this study was to investigate the oxidative and apoptotic potential of fluoxetine, a widely used antidepressant in Turkey and the world, and of its metabolite norfluoxetine on a model non-target organism, Daphnia magna to see how exposure to ...

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

open access: yesAdvanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,
