Phosphorylation of cytochrome c at tyrosine 48 finely regulates its binding to the histone chaperone SET/TAF‐Iβ in the nucleus

open access: yesProtein Science, Volume 33, Issue 12, December 2024.
Abstract Post‐translational modifications (PTMs) of proteins are ubiquitous processes present in all life kingdoms, involved in the regulation of protein stability, subcellular location and activity. In this context, cytochrome c (Cc) is an excellent case study to analyze the structural and functional changes induced by PTMS as Cc is a small ...

Imaging of heme/hemeproteins in nucleus of the living cells expressing heme-binding nuclear receptors

open access: yes, 2013
Several factors involved in the core circadian rhythm are PAS domain proteins, one of which, neuronal PAS2 (NPAS2), contains a heme-binding motif. It is thought that heme controls the transcriptional activity of core circadian factors BMAL1-NPAS2, and ...

Access and Binding of H2S to Hemeproteins: The Case of HbI of Lucina pectinata [PDF]

open access: yes, 2016
Hydrogen sulfide (H2S) was recently discovered as a gasotransmitter, capable of coordinating to the heme iron of hemeproteins. H2S is unique for its ability to render varying concentrations of the nucleophilic conjugate bases (HS- or S2-), either as free

Binding mechanism of disulfide species to ferric hemeproteins: The case of metmyoglobin

open access: yes, 2023
The interactions of the heme iron of hemeproteins with sulfide and disulfide compounds are of potential interest as physiological signaling processes. While the interaction with hydrogen sulfide has been described computationally and experimentally, the ...

Role of the Circadian Gas-Responsive Hemeprotein NPAS2 in Physiology and Pathology

open access: yesBiology, 2023
Neuronal PAS domain protein 2 (NPAS2) is a hemeprotein comprising a basic helix–loop–helix domain (bHLH) and two heme-binding sites, the PAS-A and PAS-B domains. This protein acts as a pyridine nucleotide-dependent and gas-responsive CO-dependent transcription factor and is encoded by a gene whose expression fluctuates with circadian rhythmicity. NPAS2

Porphyrin Atropisomerism as a Molecular Engineering Tool in Medicinal Chemistry, Molecular Recognition, Supramolecular Assembly, and Catalysis

open access: yesChemistry – A European Journal, Volume 30, Issue 43, August 1, 2024.
Porphyrin atropisomerism opens an entirely new toolbox, allowing for the precise design of a porphyrin's molecular shape. This review details how this phenomenon has been utilised across all fields of chemistry, focusing on molecular recognition, medicinal chemistry and catalysis.

The flavohemoglobin Yhb1 is a new interacting partner of the heme transporter Str3

open access: yesMolecular Microbiology, Volume 122, Issue 1, Page 29-49, July 2024.
A new mechanism for Yhb1 (orange) heme‐dependent activation involves direct interaction with the cell‐surface heme transporter Str3 (blue) in the presence of exogenous heme (red). Upon exposure to nitric oxide (˙NO), the expression of yhb1+ is induced, as its promoter is liberated from Fep1 repression (violet).

Organic Cyanide Decorated SERS Active Nanopipettes for Quantitative Detection of Hemeproteins and Fe3+ in Single Cells

open access: yes, 2017
It is challenging to develop a robust nanoprobe for real-time operational and accurate detection of heavy metals in single cells. Fe-CN coordination chemistry has been well studied to determine the structural characteristics of hemeproteins by different ...
