Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

open access: yesAdvanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

Engineering Electron Transfer Flux between Cytochrome P450 Enzyme and P450 Reductase to Enhance Serotonin Production in Escherichia Coli

open access: yesAdvanced Science, EarlyView.
The electron transfer flux in CPR‐P450 catalytic system is systematically engineered through: i) enhancing electron transfer rate by redesigning the putative electron transfer pathway of CPR; ii) improving electron‐receiving rate by evolving the heme domain of tryptophan‐5‐hydroxylase (T5H); iii) enlarging electron supply by fine‐tuning NADPH synthesis.

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

open access: yesAdvanced Science, EarlyView.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

Responsive ROS‐Augmented Prodrug Hybridization Nanoassemblies for Multidimensionally Synergitic Treatment of Hepatocellular Carcinoma in Cascade Assaults

open access: yesAdvanced Science, EarlyView.
This study proposes a novel HCC therapy using CA‐4S2@ES‐Cu nanomedicines to amplify cuproptosis, enhancing chemotherapy and immunotherapy. CA‐4 and ES‐Cu synergistically inhibit tumor growth, induce immune responses, and reverse the immunosuppressive microenvironment, offering an effective multidimensional therapeutic strategy for HCC treatment ...

Cyanophenylalanine as an Infrared Probe for Iron–Sulfur Cluster Redox State in Multicenter Metalloenzymes

open access: yesChemBioChem, EarlyView.
The noncanonical amino acid, cyanophenylalanine, is genetically inserted close to iron–sulfur clusters of either spinach ferredoxin or iron–iron hydrogenase, and functions as an infrared spectroscopic reporter for changes in cluster redox state.

Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

open access: yesChemistry – A European Journal, EarlyView.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

The Impact of Redox Mediators on the Electrogenic and Physiological Properties of Synechocystis sp. PCC 6803 in a Biophotovoltaic System

open access: yesChemSusChem, EarlyView.
Redox mediators are essential to promote the electrogenic activity of cyanobacteria in biophotovoltaics. In this work, we systematically evaluates three representative mediators about their influence on the cyanobacterial growth, photosynthetic efficiency, and electrogenic activity. The results reveal distinct impacts of different mediators, despite of

Spatial Isolation of Single Copper(I) Sites for Cascade Enzyme‐Like Catalysis and Simultaneous Ferroptosis/Cuproptosis Boosted Immunotherapy

open access: yesExploration, EarlyView.
Self‐assembled S‐Cu(I)‐S sites were spatially isolated onto a two‐dimensional Ti3C2 surface to produce a structurally well‐defined and highly functional single‐site copper(I) nanomodulator CuNTD, which can induce severe immunogenic cell death through multiple regulatory pathways of synergistic cascade photothermal‐amplified ROS storms, cuproptosis and ...

Analysis of Benzoate 1,2‐Dioxygenase Identifies Shared Electron Transfer Components With DxnA1A2 in Rhizorhabdus wittichii RW1

open access: yesJournal of Basic Microbiology, EarlyView.
ABSTRACT Rhizorhabdus wittichii RW1 is known for its ability to degrade polycyclic aromatic hydrocarbons, such as dibenzo‐p‐dioxin (DD) and dibenzofuran (DF). We hypothesized that the R. wittichii RW1 benzoate 1,2‐dioxygenase shares electron transfer components with the DD/DF angular dioxygenase (DxnA1A2), similar to many aromatic hydrocarbon degrading
