Sequence similarity network reveals the imprints of major diversification events in the evolution of microbial life

open access: yesFrontiers in Ecology and Evolution, 2014
Ancient transitions, such as between life that evolved in a reducing versus an oxidizing atmosphere precipitated by the Great Oxygenation Event (GOE) ca.

Enzyme-Based Biosensors: Tackling Electron Transfer Issues

open access: yesSensors, 2020
This review summarizes the fundamentals of the phenomenon of electron transfer (ET) reactions occurring in redox enzymes that were widely employed for the development of electroanalytical devices, like biosensors, and enzymatic fuel cells (EFCs). A brief

In Escherichia coli Ammonia Inhibits Cytochrome bo3 But Activates Cytochrome bd-I

open access: yesAntioxidants, 2020
Interaction of two redox enzymes of Escherichia coli, cytochrome bo3 and cytochrome bd-I, with ammonium sulfate/ammonia at pH 7.0 and 8.3 was studied using high-resolution respirometry and absorption spectroscopy. At pH 7.0, the oxygen reductase activity

Harnessing redox proteomics to study metabolic regulation and stress response in lignin-fed Rhodococci

open access: yesBiotechnology for Biofuels and Bioproducts, 2023
Background Rhodococci are studied for their bacterial ligninolytic capabilities and proclivity to accumulate lipids. Lignin utilization is a resource intensive process requiring a variety of redox active enzymes and cofactors for degradation as well as ...

Peptide self‐assembly as a strategy for facile immobilization of redox enzymes on carbon electrodes

open access: yesCarbon Energy, 2023
Redox–enzyme‐mediated electrochemical processes such as hydrogen production, nitrogen fixation, and CO2 reduction are at the forefront of the green chemistry revolution. To scale up, the inefficient two‐dimensional (2D) immobilization of redox enzymes on

Cysteine-Based Redox Switches in Enzymes [PDF]

open access: yesAntioxidants & Redox Signaling, 2011
The enzymes involved in metabolism and signaling are regulated by posttranslational modifications that influence their catalytic activity, rates of turnover, and targeting to subcellular locations. Most prominent among these has been phosphorylation/dephosphorylation, but now a distinct class of modification coming to the fore is a

Highly Promiscuous Oxidases Discovered in the Bovine Rumen Microbiome

open access: yesFrontiers in Microbiology, 2018
The bovine rumen hosts a diverse microbiota, which is highly specialized in the degradation of lignocellulose. Ruminal bacteria, in particular, are well equipped to deconstruct plant cell wall polysaccharides.
