Lactiplantibacillus plantarum uses ecologically relevant, exogenous quinones for extracellular electron transfer

open access: yesmBio, 2023
Extracellular electron transfer (EET) is a metabolic process that frequently uses quinones to couple intracellular redox reactions with extracellular electron acceptors. The physiological relevance of this metabolism for microorganisms capable of EET but

Simultaneous and Spontaneous Oxidation and Reduction in Microdroplets by the Water Radical Cation/Anion Pair

open access: yesAngewandte Chemie, 2022
Microdroplets show unique chemistry, especially in their intrinsic redox properties, and to this we here add a case of simultaneous and spontaneous oxidation and reduction.

Use of an Anaerobic Chamber Environment for the Assay of Endogenous Cellular Protein-Tyrosine Phosphatase Activities

open access: yesBiological Procedures Online, 2002
Protein-tyrosine phosphatases (PTPases) have a catalytic cysteine residue whose reduced state is integral to the reaction mechanism. Since exposure to air can artifactually oxidize this highly reactive thiol, PTPase assays have typically used potent ...

Formation and Cleavage of C-C Bonds by Enzymatic Oxidation-Reduction Reactions.

open access: yesChemical Reviews, 2018
Many oxidation-reduction (redox) enzymes, particularly oxygenases, have roles in reactions that make and break C-C bonds. The list includes cytochrome P450 and other heme-based monooxygenases, heme-based dioxygenases, nonheme iron mono- and dioxygenases,

Oxidation-reduction potential as a new marker for oxidative stress: Correlation to male infertility

open access: yesInvestigative and Clinical Urology, 2017
Male infertility affects men worldwide. Oxidative stress (OS), characterized by an overabundance of reactive oxygen species (ROS) or a deficiency of antioxidants, is one of the major causes of male infertility.
