The acidic domain of cytochrome c₁ in paracoccus denitrificans, analogous to the acidic subunits in eukaryotic bc₁ complexes, is not involved in the electron transfer reaction to its native substrate cytochrome c(552).

Abstract

The cytochrome bc(1) complex is a key component in several respiratory pathways. One of the characteristics of the eukaryotic complex is the presence of a small acidic subunit, which is thought to guide the interaction of the complex with its electron acceptor and facilitate electron transfer. Paracoccus denitrificans represents the only example of a… (More)
