Protein Of The Month

March: Cytochrome c
Origin: Cytochrome c is primarily known as an electron-carrying mitochondrial protein. It is ubiquitous in nature and shares sequence homologies across many species.
Application: Cytochrome c is commonly used as a protein standard for several applications. Cytochrome c has been identified as a mediator in apoptosis, and also suggested as a biomarker for the oxidative environment in a cell.
How: The transition of cytochrome c between the ferrous and ferric states within the cell makes it an efficient biological electron-transporter. It plays a vital role in cellular oxidations in both plants and animals.
Did you know: Cytochrome c oxidase contributes to the O2 uptake rate by vegetables. It is also one of the important causes for variation in O2 uptake rates among vegetables.
