Application
Cytochrome c has been used:
- in the reduction of ferricytochrome c by xanthine oxidase-generated superoxide radicals
- as an analyte by the single droplet deposition method using MALDI mass spectra
- as a terminal electron acceptor in the assay of standard cytochrome c reductase activity
- in cytochrome c oxidase histochemistry
- in the measurement of cytochrome C oxidase activity
- as a component of phosphate buffer for the detection and evaluation of complex IV activity using blue-native gel electrophoresis (BN-PAGE)
- for detection of extracellular superoxide anion (ECSA) in isolated kidney phagocytes
The specific sites and extent of oxidation in horse cytochrome c treated with H2O2 and UV were characterized. It was suggested that the state of these sites could be used as a biomarker for the oxidative environment in a cell.
Biochem/physiol Actions
Cytochrome c is primarily known as an electron-carrying mitochondrial protein. The transition of cytochrome c between the ferrous and ferric states within the cell makes it an efficient biological electron-transporter and it plays a vital role in cellular oxidations in both plants and animals. It is generally regarded as a universal catalyst of respiration, forming an essential electron-bridge between the respirable substrates and oxygen
Cytochrome c, released from the outer mitochondrial compartment into the cytosol aids in activation of caspase-9 and initiation of the apoptotic protease cascade. This process is facilitated through its interaction with apoptotic protease-activating factor-1 (APAF-1) and deoxyadenosine triphosphate (dATP).(3) Various studies suggest that measurement of cytochrome C level in serum of tumor patients can be considered as a potential marker for cell death in vivo.

Toxoplasma gondii possesses an apicoplast-localized, plant-type ferredoxin-NADP(+) reductase. We have cloned a [2Fe-2S] ferredoxin from the same parasite to investigate the interplay of the two redox proteins.
