NMR analysis of the transient complex between membrane photosystem I and soluble cytochrome c6
(Elsevier, 2005)
A structural analysis of the surface areas of cytochrome c6, responsible for the transient interaction with photosystem I, was performed by NMR transverse relaxation-optimized spectroscopy. The hemeprotein was titrated by ...

Structural and Functional Analysis of Novel Human Cytochrome c Targets in Apoptosis
(American Society for Biochemistry and Molecular Biology, 2014)
Since the first description of apoptosis four decades ago, great efforts have been made to elucidate, both in vivo and in vitro, the molecular mechanisms involved in its regulation. Although the role of cytochrome c during ...

Structural basis for inhibition of the histone chaperone activity of SET/TAF-Iβ by cytochrome c
(National Academy of Sciences, 2015)
Chromatin is pivotal for regulation of the DNA damage process insofar as it influences access to DNA and serves as a DNA repair docking site. Recent works identify histone chaperones as key regulators of damaged chromatin’s ...

Oxidizing Side of the Cyanobacterial Photosystem I
(Elsevier, 1999)
Photosystem I (PSI) interacts with plastocyanin or cytochrome c 6 on the luminal side. To identify sites of interaction between plastocyanin/cytochromec 6 and the PSI core, site-directed mutations were generated in the ...

Voltammetric study of the adsorbed thermophilic plastocyanin from Phormidium laminosum up to 90 °c
(Elsevier, 2012)
Redox thermodynamics and kinetics of plastocyanin from Phormidium laminosum, and of azurin from Pseudonomas aeruginosa, have been investigated as a function of temperature by protein film voltammetry. To this purpose, both ...

Site-directed Mutagenesis of Cytochromec 6 from Anabaena Species PCC 7119
(Elsevier, 1999)
A number of surface residues of cytochromec 6 from the cyanobacterium Anabaenasp. PCC 7119 have been modified by site-directed mutagenesis. Changes were made in six amino acids, two near the heme group (Val-25 and Lys-29) ...

New Arabidopsis thaliana cytochrome c partners: A look into the elusive role of cytochrome c in programmed cell death in plants
(American Society for Biochemistry and Molecular Biology, 2013)
Programmed cell death is an event displayed by many different organisms along the evolutionary scale. In plants, programmed cell death is necessary for development and the hypersensitive response to stress or pathogenic ...

Temperature-driven changeover in the electron-transfer mechanism of a thermophilic plastocyanin
(American Chemical Society, 2014)
Electron-transfer kinetics of the thermophilic protein Plastocyanin fromPhormidium laminosumadsorbed on 1,ω-alkanedithiol self-assembled monolayers (SAMs)deposited on gold have been investigated. The standard electron-transfer ...

Antimalarial activity of cupredoxins: the interaction of Plasmodium Merozoite Surface Protein 119 (MSP119) and Rusticyanin
(American Society for Biochemistry and Molecular Biology, 2013)
Background: The interaction of MSP119 with the cupredoxin azurin inhibits the growth of Plasmodium falciparum in red blood cells. Results: Rusticyanin forms a well-defined complex with MSP119 upon binding at the same surface ...

Specific nitration of tyrosines 46 and 48 makes cytochrome c assemble a non-functional apoptosome
(Elsevier, 2012)
Under nitroxidative stress, a minor fraction of cytochrome c can be modified by tyrosine nitration. Here we analyze the specific effect of nitration of tyrosines 46 and 48 on the dual role of cytochrome c in cell survival ...
