*  The ionic strength dependence of the reduction of cytochrome c peroxidase compound I by horse heart ferrocytochrome c
The ionic strength dependence of the reduction of cytochrome c peroxidase compound I by horse cytochrome c has been studied, using stopped-flow technigue, in pH 7.5, potassium phosphate/nitrate buffer. The temperature was set at 25 ± 1° C. The wavelength was monitored at 4 32 nm, an isobestic point for ferri-/ferrocytochrome c, so only the absorbance change of the reduction of cytochrome c peroxidase compound I to compound II can be observed. The observed rate constant, kobs, as a function of the concentration of ferrocytochrome c shows a non-linear increase with increasing ionic strength. A two-parameter eguation is needed to fit the data at low ionic strength, 20 mM to 40 mM, while a three-parameter equation is needed at high ionic strength, 65 mM and above. The maximum rates of these reductions also show two different types of ionic strength dependence. At 20 mM to 40 mM ionic strength, ...

*  Characterization of the reaction between cytochrome c peroxidase and potassium fluoride
The reactivity of potassium fluoride with wild-type cytochrome c peroxidase (CcP) and a mutant of cytochrome c peroxidase in which the distal histidine (His-52) is replaced with leucine [CcP(H52L)] has been studied from pH 4 to 8 in phosphate buffer at 0.1 M ionic strength. The spectrum of the fluoride complex of CcP(H52L) has been characterized. The kinetics of fluoride binding and the equilibrium constant for complex formation for both wild-type CcP and CcP(H52L) have been determined as a function of pH. The results of this study indicate that HF binds to wild-type CcP when the distal histidine is unprotonated. However, the association rate constant for fluoride binding to CcP(H52L) is only a factor of ten slower than binding to CcP at pH 5.5 and about the same at pH 8.0. A possible explanation is that another group, such as Arg-48 or the heme-bound hydroxide group in CcP(H52L), provides a function similar to that of His-52 in wild-type ...

*  Characterization of cytochrome c peroxidase of Marinobacter aquaeolei :: University of Southern California Dissertations and...
The molecular biology and biochemistry of biological iron oxidation at neutral pH is poorly understood. In part this is due to the fact that most chemolithoautotrophic iron oxidizing bacteria are genetically intractable and very difficult to cultivate and manipulate in the laboratory. The Marinobacter are ubiquitous marine bacteria that occur in hydrothermal settings, including hydrothermal plumes, chimneys, and seafloor exposed basalts. Many are capable of iron oxidation and can also be readily cultivated and studied in the laboratory. We hypothesize Marinobacter aquaeolei, a lithoheterotrophic iron oxidizing bacterium, utilizes the gene cytochrome c peroxidase (CCP) for Fe-oxidation during lithoheterotrophic growth. We have characterized heme protein activity during Fe-oxidation via heme staining followed by searching NCBI for genes of interest. Our preliminary research led us to cytochrome c peroxidase, a small heme protein. We ...

Cytochrome c peroxidase was isolated from Paracoccus denitrificans and purified to homogeneity in three steps prior to crystallization. Two different diffraction-quality crystal forms were obtained by the hanging-drop vapour-diffusion method using a number of screening conditions. The best (needle-shaped) crystal form is suitable for structural studies and was grown from solutions containing 20% PEG 8000, 0.1 M Tris pH 8.5 and 0.2 M MgCl(2). Crystals grew to a maximum length of approximately 0.7 mm and belong to the primitive monoclinic space group P2(1), with unit-cell parameters a = 78.3, b = 51.0, c = 167.2 A, beta = 97.9 degrees. After a dehydration step and extensive optimization of the cryocooling conditions, a complete data set was collected to 2.2 A from a native crystal of the fully oxidized form of the enzyme using synchrotron radiation.

Reduction of fully oxidized Clostridium pasteurianum 8-Feox.,ox. ferredoxin by using pulse-radiolysis techniques yields the half-reduced species 8-Feox.,red. ferredoxin. The subsequent oxidation of 8-Feox.,red. ferredoxin with Co(NH3)5Cl2+ was studied. From a comparison with stopped-flow studies on the 2:1 Co(NH3)5Cl2+ oxidation of 8-Fered.,red. ferredoxin to the 8-Feox.,ox. form it is concluded that there is no redox co-operativity between the two 4-Fe centres in these reactions. ...

*  Hydrogen-bond effects on Proton-Coupled Electron Transfer from Phenols
Amino acid radicals are key redox intermediates in several natural enzymes including Cytochrome c peroxidase, DNA photolyase, ribonucletide reductase, cytochrome c oxidase and photosystem II. Electron transfer from amino acids is often coupled to deprotonation and this thesis concerns the coupling of electron transfer from tyrosine and tryptophan to trisbipyridineruthenium(III) with deprotonation in model complexes. Specifically the mechanisms for these proton coupled electron transfer reactions have been studied and the controlling parameters have been identified, the possible mechanisms being stepwise electron transfer followed by deprotonation and deprotonation followed by electron transfer or concerted electron transfer/deprotonation.. Proton coupled electron transfer reactions have been studied using nano-second flash photolysis in water solution and the effect of pH, temperature, reaction driving force, deuteration and nature of the amino acid has been ...

*  "Nano-grids of Yeast Cytochrome C" by Human Arjomandi
One innovative thought in biomolecular electronics is the exploitation of electron transfer proteins. Using nature's self assembly techniques, proteins can build highly organized edifices with retained functional activity, and they can serve as platforms for biosensors. In this research work, Yeast Cytochrome C (YCC) is immobilized with a help of a linker molecule, 3-Mercaptopropyltrimethoxysilane (3-MPTS) on a hydroxylated surface of a silicon substrate. Atomic Force Microscopy (AFM) is used for characterization. AFM data shows immobilization of one YCC molecule in between eight grids that are formed by the linker molecules. 3-MPTS monolayers are organized in grids that are 1.2 nm apart. Immobilization of 3-MPTS was optimized using a concentration of 5 mM in a completely dehydrated state for 30 minutes. The functionally active grids of YCC can now be incorporated with Cytochrome C oxidase on a Platinum electrode surface for transfer of electrons in development of ...

*  Mechanisms involved in the inhibition of glycolysis by cyanide and antimycin A in Candida albicans and its reversal by hydrogen...
In Candida albicans, cyanide and antimycin A inhibited K(+) transport, not only with ethanol-O2 as the substrate, but also with glucose. The reason for this was that they inhibited not only respiration, but also fermentation, decreasing ATP production. Measurements of oxygen levels in cell suspensions allowed identification of the electron pathways involved. NADH fluorescence levels increased in the presence of the inhibitors, indirectly indicating lower levels of NAD(+) and so pointing to glyceraldehyde-3-phosphate dehydrogenase as the limiting step responsible for the inhibition of glycolysis, which was confirmed by the levels of glycolytic intermediaries. The cyanide effect could be reversed by hydrogen peroxide, mainly due to an activity by which H2O2 can be reduced by electrons flowing from NADH through a pathway that can be inhibited by antimycin A, and appears to be a cytochrome c peroxidase. Therefore, the inhibition ...

*  JCI - Young endothelial cells revive aging blood
Poulos and colleagues demonstrate a decline in BM EC numbers, increased BM vascular leakiness, and elevated intracellular ROS levels in ECs from aged (24-month-old) C57BL/6 mice compared with those from young (3-month-old) mice. Furthermore, aged BM ECs displayed decreased proliferative and angiogenic potential and decreased expression of paracrine factors, including stem cell factor, CXCL12, and Jagged1, which are integral to the HSC-supportive function of BM ECs (6-9). Utilizing an ex vivo model to test the hematopoietic-instructive function of BM ECs, Poulos et al. showed that coculture of young BM progenitor cells with aged BM ECs caused a decline in the HSC-repopulating capacity, while coculture of aged BM progenitor cells with young ECs rescued the HSC-repopulating capacity, albeit incompletely.. In a series of in vivo experiments, Poulos and colleagues demonstrated that serial infusions of aged BM ECs failed to rescue HSC content in young mice following high-dose total body irradiation, ...
