Dimerization model of the C-terminal RNA Recognition Motif of HuR
(wiley, 2015)
Human antigen R (HuR) is a ubiquitous 32kDa protein comprising three RNA Recognition Motifs (RRMs), whose main function is to bind Adenylate and uridylate Rich Elements (AREs) in 3′ UnTranslated Regions (UTRs) of mRNAs. ...

Site-directed Mutagenesis of Cytochromec 6 from Synechocystissp. PCC 6803
(Elsevier, 1999)
This paper reports the first site-directed mutagenesis analysis of any cytochrome c 6, a heme protein that performs the same function as the copper-protein plastocyanin in the electron transport chain of photosynthetic ...

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 ...

Structure of the Complex between Plastocyanin and Cytochrome f from the Cyanobacterium Nostoc sp. PCC 7119 as Determined by Paramagnetic NMR
(Elsevier, 2005)
The complex between cytochrome f and plastocyanin from the cyanobacterium Nostoc has been characterized by NMR spectroscopy. The binding constant is 16 mm–1, and the lifetime of the complex is much less than 10 ms. ...

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 ...

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 ...

Proposed mechanism for regulation of H2O2-induced programmed cell death in plants by binding of cytochrome c to 14-3-3 proteins
(Wiley-Blackwell, 2021-04)
Programmed cell death (PCD) is crucial for development and homeostasis of all multicellular organisms. In human cells, the double role of extra-mitochondrial cytochrome c in triggering apoptosis and inhibiting survival ...
