Molecular Crowding Affects the Conformational Fluctuations, Peroxidase Activity, and Folding Landscape of Yeast Cytochrome c.

Biochemistry, 2016
To understand how a protein folds and behaves inside living cells, the effects of synthetic crowding media on protein folding, function, stability, and association have been studied in detail. Because the effect of excluded volume is more prominent in an

Unusually high thermal stability and peroxidase activity of cytochrome c in ionic liquid colloidal formulation.

Chemical Communications, 2016
Ionic liquid (IL) surfactant choline dioctylsulfosuccinate, [Cho][AOT], formed polydispersed vesicular structures in the IL, ethylmethylimidazolium ethylsulfate, [C2mim][C2OSO3].

Interactions of Cytochrome c Peroxidase with Lysine Peptides

Biochemical and Biophysical Research Communications, 2000
Structural change of Cytochrome c peroxidase (CcP) due to interaction with lysine peptides (Lysptds) has been studied by absorption spectra and measurements on electron transfer between cytochrome c (cyt c) and CcP in the presence of Lysptd. Peaks were observed in the difference absorption spectrum of CcP between in the presence and absence of Lysptds,

Ionic liquid-induced all-α to α + β conformational transition in cytochrome c with improved peroxidase activity in aqueous medium.

Physical Chemistry, Chemical Physics - PCCP, 2015
Choline dioctylsulfosuccinate [Cho][AOT] (a surface active ionic liquid) has been found to induce all-α to α + β conformational transition in the secondary structure of enzyme cytochrome c (Cyt c) with an enhanced peroxidase activity in its aqueous ...

The cytochrome c peroxidase of Paracoccus denitrificans

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1991
The size, visible absorption spectra, nature of haem and haem content suggest that the cytochrome c peroxidase of Paracoccus denitrificans is related to that of Pseudomonas aeruginosa. However, the Paracoccus enzyme shows a preference for cytochrome c donors with a positively charged 'front surface' and in this respect resembles the cytochrome c ...

The catalytic mechanism of Pseudomonas cytochrome c peroxidase

Archives of Biochemistry and Biophysics, 1981
Abstract The catalytic mechanism of Pseudomonas cytochrome c peroxidase has been studied using rapid-scan spectrometry and stopped-flow measurements. The reaction of the totally ferric form of the enzyme with H 2 O 2 was slow and the complex formed was inactive in the peroxidatic cycle, whereas partially reduced enzyme formed highly reactive ...

A novel colorimetric method for the detection of Escherichia coli using cytochrome c peroxidase-encoding bacteriophage.

FEMS Microbiology Letters, 2014
A new rapid and simple method was developed for the detection of Escherichia coli by constructing a recombinant T4 phage carrying the cytochrome c peroxidase gene derived from Saccharomyces cerevisiae (T4ccp) using which, the colorimetric detection of E.

Cytochrome c and cytochrome c peroxidase complex as studied by resonance Raman spectroscopy

Biochemistry, 1992
Complex formation between ferricytochrome c peroxidase (CCP) and ferricytochrome c from yeast [cyt(Y)] and horse heart [cyt(H)] was studied by resonance Raman spectroscopy. On the basis of a detailed spectral analysis of the free proteins, it was possible to attribute changes in the spectra of the complexes to the individual proteins.

Cytochrome c peroxidase binds two molecules of cytochrome c: Evidence for a low-affinity, electron-transfer-active site on cytochrome c peroxidase

Biochemistry, 1993
We have studied the affinity and stoichiometry of binding of cytochrome c (Cc) to zinc-substituted cytochrome c peroxidase [(ZnP)CcP], which is structurally and electrostatically equivalent to ferrous CcP. Transient absorption spectroscopy has been used to measure both the total quenching of the triplet-state (ZnP)CcP [3(ZnP)CcP] by Fe3+Cc and the ...

Investigation of Electron Tunneling Between Cytochrome c Peroxidase and Cytochrome c

Science, 1978
The nature of electron transfer between the bound complex cytochrome c and cytochrome c peroxidase has been investigated. Experimental verification of the predicted charge-transfer band provides evidence of electron tunneling as the mechanism of transfer between these molecules in solution at room temperature.
