Communication between L–galactono–1,4–lactone dehydrogenase and cytochrome c
(Wiley: FEBS Journal, 2013-02-25)
l‐galactono‐1,4‐lactone dehydrogenase (GALDH) catalyzes the terminal step of vitamin C biosynthesis in plant mitochondria. Here we investigated the communication between Arabidopsis thaliana GALDH and its natural electron ...

The dynamic complex of cytochrome c6 and cytochrome f studied with paramagnetic NMR spectroscopy
(Elsevier B.V., 2014)
The rapid transfer of electrons in the photosynthetic redox chain is achieved by the formation of short-lived complexes of cytochrome b6f with the electron transfer proteins plastocyanin and cytochrome c6. A balance must ...

Cytochrome c signalosome in mitochondria
(Springer, 2011)
Cytochrome c delicately tilts the balance between cell life (respiration) and cell death (apoptosis). Whereas cell life is governed by transient electron transfer interactions of cytochrome c inside the mitochondria, the ...

The cytochrome f–plastocyanin complex as a model to study transient interactions between redox proteins
(Wiley, 2012)
Transient complexes, with a lifetime ranging between microseconds and seconds, are essential forbiochemical reactions requiring a fast turnover. That is the case of the interactions between proteinsengaged in electron ...

Cytochrome c1 exhibits two binding sites for cytochrome c in plants
(Elsevier, 2014)
n plants, channeling of cytochrome c molecules between complexes III and IV has been purported to shuttle electrons within the supercomplexes instead of carrying electrons by random diffusion across the intermembrane bulk ...
Artículo
Respiratory complexes III and IV can each bind two molecules of cytochrome c at low ionic strength
(Elsevier, 2015)
The transient interactions of respiratory cytochrome c with complexes III and IV is herein investigated by using heterologous proteins, namely human cytochrome c, the soluble domain of plant cytochrome c1 and bovine ...

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 ...

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 ...

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 ...
