Cytochrome P is a superfamily of membrane-bound hemoprotein that gets involved with the degradation of xenobiotics and internal metabolites. Accumulated body of evidence indicates that phospholipids play a crucial role in determining the enzymatic activity of cytochrome P in the microenvironment by modulating its structure during detoxification; however, the structure-function Cited by: 7.

Binding of cytochrome c (cytc) to fatty acids and acidic phospholipid membranes produces pronounced and essentially identical changes in the spectral properties of cyt c, revealing conformational changes in the exact mechanism of the interaction of fatty acids and acidic phospholipids with cyt c is by: Cytochrome P aromatic O-demethylase, which is made of two distinct promiscuous parts: a cytochrome P protein (GcoA) and three domain reductase, is significant for its ability to convert Lignin, the aromatic biopolymer common in plant cell walls, into renewable carbon chains in a catabolic set of reactions.
In short, it is a facilitator of. Cytochrome c (cytc) 1 is a mitochondrial peripheral membrane protein functioning in the respiratory chain in the inner mitochondrial membrane. With its heme moiety switching between ferro and ferri forms, this water-soluble kDa protein shuttles electrons from cyt c reductase to cyt c oxidase.
