Cytochrome c in plants
Did you know?
Cytochrome c is a highly conserved protein across the spectrum of eukaryotic species, found in plants, animals, fungi, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), makes it useful in studies of cladistics.

WebNov 1, 2014 · Mitochondrial membrane permeabilization, leading to the release of cytochrome c and other pro-apoptotic factors into the cytosol, is regulated by the interaction between pro- and anti-apoptotic Bcl-2 family members (e.g. Bax, Bim, Bcl-XL, among others) ( Narita et al., 1998 ). WebAbstract. It is generally recognized that the multiplicity of cytochrome P450 forms in animals, especially those of the CYP2 family, is largely the result of the coevolution of plants and phytophageous animals.
