Bio-Electroanalysis Performance of Heme Redox-Center for π-π Interaction Bonding of a Methylene Blue-Graphene Modified Electrode [PDF]

open access: yesNanomaterials, 2023
Hemeprotein detection has motivated extensive research on the direct reaction of a heme molecule and a redox dye. The present study used methylene blue as both donor and acceptor for a redox reaction.

Low levels of nitric oxide promotes heme maturation into several hemeproteins and is also therapeutic [PDF]

open access: yesRedox Biology, 2022
Nitric oxide (NO) is a signal molecule and plays a critical role in the regulation of vascular tone, displays anti-platelet and anti-inflammatory properties.

Heme allocation in eukaryotic cells relies on mitochondrial heme export through FLVCR1b to cytosolic GAPDH [PDF]

open access: yesNature Communications
Heme is an iron-containing cofactor generated in mitochondria that must leave this organelle to reach protein targets in other cell compartments. Because mitochondrial heme binding by cytosolic GAPDH enables its distribution in cells, we sought to ...

Incorporation of silver stearate nanoparticles in methacrylate polymeric monoliths for hemeprotein isolation

open access: goldOpen Chemistry, 2020
A unique method was used to synthesize extremely stable silver stearate nanoparticles (AgStNPs) incorporated in an organic-based monolith. The facile strategy was then used to selectively isolate hemeproteins, myoglobin (Myo)

Light‐Induced Pulsed EPR Dipolar Spectroscopy on a Paradigmatic Hemeprotein [PDF]

open access: hybridChemPhysChem, 2019
AbstractLight‐induced pulsed EPR dipolar spectroscopic methods allow the determination of nanometer distances between paramagnetic sites. Here we employ orthogonal spin labels, a chromophore triplet state and a stable radical, to carry out distance measurements in singly nitroxide‐labeled human neuroglobin.

Hsp90 in Human Diseases: Molecular Mechanisms to Therapeutic Approaches [PDF]

open access: yesCells, 2022
The maturation of hemeprotein dictates that they incorporate heme and become active, but knowledge of this essential cellular process remains incomplete. Studies on chaperon Hsp90 has revealed that it drives functional heme maturation of inducible nitric

Influence of the freezing process upon fluoride binding to hemeproteins

open access: bronzeBiophysical Journal, 1991
Fluoride association with ferric myoglobins and hemoglobins in aqueous buffers above freezing has been well studied. We chose this reaction to investigate the feasibility of observing titration intermediates and estimating dissociation constants at the freezing temperature by electron paramagnetic resonance spectroscopy at cryogenic temperatures ...
