Description

Application

Protein calibration standard for MALDI-MS instruments.

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
