Cytochrome p-450

Cytochrome p-450

(Science: biochemistry) enzymes of the electron transport chain that are pigmented by virtue of their haem prosthetic groups.

They are highly conserved isozymes which are key components of the mixed-function oxidase system responsible for the biotransformation of many foreign compounds to mutagens and carcinogens.

Most mammals have several distantly related phenobarbital-inducible gene subfamilies.

Re: Intrinsic apoptosis in erythrocytes

Thanks very much for your responses. They do not have genes to activate release of cytochrome c (even then, Im not sure how they would without mitochondria. If they were to do that, they'd probably use Bax or Bak as enzyme linked receptors to kick of a MAP kinase ...
