Cytochrome-c (cyt-c) is an electron transport protein, and it is present throughout the evolution. More than 280 sequences have been reported in the protein sequence database (www.uniprot.org). Though sequentially diverse, cyt-c has essentially retained its tertiary structure or fold. Thus a vast data set of varied sequences with retention of similar structure and fun...
Objective(s): The present work deals with the preparation of nanobioconjugates based on the immobilization of cytochrome c (cyt c) on functionalized multi-wall carbon nanotubes (f-MWCNTs). The effect of the nanosupport and the immobilization procedure on the biochemical and structural characteristics of the immobilized protein was investigated. Methods: </strong...
cytochrome-c (cyt-c) is an electron transport protein, and it is present throughout the evolution. more than 280 sequences have been reported in the protein sequence database (www.uniprot.org). though sequentially diverse, cyt-c has essentially retained its tertiary structure or fold. thus a vast data set of varied sequences with retention of similar structure and function makes it a primary ca...
Cytochrome c (cyt c)-immobilized monolayers and multiple monolayers of a conducting polymer [poly(terthiophene-3-carboxylic acid) polymer (poly-TTCA)] were prepared, where the monolayer of monomer precursor was fabricated with the Langmuir-Blogett technique. Covalent immobilization of cyt c was achieved by the formation of an amide bond between the carboxylic groups of the conducting polymer an...
The interaction of cytochrome c (cyt c) with poly(isobutylene-alt-maleic acid) (PIMA) and poly(1-tetradecene-alt-maleic acid) (PTMA) was studied using circular dichroism, absorption spectroscopy, and atomic force microscopy to investigate the electrostatic and hydrophobic influence of the copolymers on the structure of cyt c. At pH 7.4, the interaction of PIMA with cyt c can only partly disturb...
Reactive halogen species (RHS; X(2) and HOX, where X represents Cl, Br, or I) are metabolites mediated by neutrophil activation and its accompanying respiratory burst. We have investigated the interaction between RHS and mitochondrial cytochrome c (cyt c) by using electrospray mass spectrometry and electron spin resonance (ESR). When the purified cyt c was reacted with an excess amount of hypoc...

The surface pressure was measured as a function of area/molecule for chlorophyll a (Chi) and cytochrome c (Cyt) at a heptane-water interface. At a surface pressure of 6 dyn/cm the area per molecule of C h l(^6) =113 ±6 Ä2, for reduced Cyt c (red. Cyt) the A6 = 5000 ± 300 Ä2 and for oxidized Cyt c (ox. Cyt) /3(6=4100 ± 250 A2. Cyt appears to denature at the interface. Irradiation results in a de...
An early event in the induction of apoptosis is cytochrome c (Cyt c) release from mitochondria. We investigated the involvement of mitochondrial permeability transition (MPT) and mitochondrial swelling in Cyt c release from mitochondria treated with alloxan and/or calcium (Ca). When mitochondria were treated with a high concentration of Ca alone or Ca with alloxan (alloxan-Ca), the MPT was acco...
Membrane association of cytochrome c (cyt c) was monitored by the efficiency of resonance energy transfer from a pyrene-fatty acid containing phospholipid derivative (1-palmitoyl-2[6-(pyren-1-yl)]hexanoyl-sn-glycero-3-phosphocholine (PPHPC)) to the heme of cyt c. Liposomes consisted of 85 mol% egg phosphatidylcholine (egg PC), 10 mol% cardiolipin, and 5 mol% PPHPC. Cardiolipin was necessary for...
