应用
Cytochrome c has been identified as an important mediator in apoptotic pathways. The release of mitochondrial cytochrome c into the cytoplasm stimulates apoptosis and is commonly used as an indicator of the apoptotic process in the cell. Investigation on the effect of Paris Saponin I (PS I) on human gastric carcinoma cell growth (SGC7901 cells) have shown an elevated level cytoplasmic cytochrome c. Results are an inhibition of proliferation in SGC7901 cells by inducing mitochondria-dependent apoptosis through cytochrome c.
生化/生理作用
The ready fluctuation of cytochrome c within the cell between ferrous and ferric states, makes it an efficient biological electron-transporter. It plays a vital role in cellular oxidations in both plants and animals. Generally regarded as a universal catalyst of respiration, it forms the essential electron-bridge between the respirable substrates and oxygen.
制备说明
Prepared with acetic acid without using TCA.

To investigate the anti-tumor effects of Paris chinensis dioscin (PCD) and mechanisms regarding cell cycle regulation and apoptosis in human gastric cancer SGC-7901 cells. Cell viability was analyzed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. Cell apoptosis was evaluated by flow cytometry

Here we present the preparation, biophysical characterization, and nuclear magnetic resonance (NMR) spectroscopy study of yeast cytochrome c peroxidase (CcP) constructs with enhanced solubility. Using a high-yield Escherichia coli expression system, we routinely produced uniformly labeled [(2)H,(13)C,(15)N]CcP samples with high

The release of cytochrome c from mitochondria is a key signaling mechanism in apoptosis. Although extramitochondrial proteins are thought to initiate this release, the exact mechanisms remain unclear. Cytochrome c (cyt c) binds to and penetrates lipid structures containing the

The membrane-bound enzyme cNOR (cytochrome c dependent nitric oxide reductase) catalyzes the reduction of NO in a non-electrogenic process. This is in contrast to the reduction of O2 in cytochrome c oxidase (CcO), the other member of the heme-copper oxidase

The biogenesis of c-type cytochromes (Cytc) is a process that in Gram-negative bacteria demands the coordinated action of different periplasmic proteins (CcmA-I), whose specific roles are still being investigated. Activities of Ccm proteins span from the chaperoning of heme b
