Oxidative inactivation of ring-cleavage extradiol dioxygenases : mechanism and ferredoxin-mediated reactivation [PDF]

, 2009
Extradiol dioxygenases are ubiquitous enzymes that catalyze ring cleavage of a wide variety of aromatic compounds. Most of these enzymes contain a ferrous ion at the active site, which is bound to the polypeptide chain through a conserved triad of two ...

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...

Metabolic and proteomic analyses of product selectivity and redox regulation in Clostridium pasteurianum grown on glycerol under varied iron availability

Microbial Cell Factories, 2017
Background Clostridium pasteurianum as an emerging new microbial cell factory can produce both n-butanol (BuOH) and 1,3-propanediol (1,3-PDO), and the pattern of product formation changes significantly with the composition of the culture medium.

Expression of the minor isoform pea ferredoxin in tobacco alters photosynthetic electron partitioning and enhances cyclic electron flow [PDF]

, 2012
Ferredoxins (Fds) are ferrosulfoproteins that function as low-potential electron carriers in plants. The Fd family is composed of several isoforms that share high sequence homology but differ in functional characteristics.

Integrated spherical nucleic acid nanoreactor mobilizes targeted PD‐L1 proteolysis and cuproptosis for robust breast cancer immunotherapy

BMEMat, EarlyView.
This study provides an integrated spherical nucleic acid nanoreactor (denoted as AMCuD) for targeted PD‐L1 degradation and chemo‐dynamically enhanced cuproptosis to synergically elicit robust immunotherapy against the triple‐negative breast cancer (TNBC) growth, recurrence and metastasis.

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

Food Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Iron-sulphur protein catalysed [4+2] cycloadditions in natural product biosynthesis

Nature Communications
To the best of our knowledge, enzymes that catalyse intramolecular Diels-Alder ([4+2] cycloaddition) reactions are frequently reported in natural product biosynthesis; however, no native enzymes utilising Lewis acid catalysis have been reported ...

A structural phylogeny for understanding 2-oxoacid oxidoreductase function [PDF]

, 2018
2-Oxoacid:ferredoxin oxidoreductases (OFORs) are essential enzymes in microbial one-carbon metabolism. They use thiamine pyrophosphate to reversibly cleave carbon-carbon bonds, generating low potential (~-500 mV) electrons. Crystallographic analysis of a
