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 ...

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]
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
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
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

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