Biogenesis of cytochrome c oxidase

Mitochondrion, 2005
Cytochrome c oxidase (COX), the terminal enzyme of electron transport chains in some prokaryotes and in mitochondria, has been characterized in detail over many years. Recently, a number of new data on structural and functional aspects as well as on COX biogenesis emerged.

ABC transporters associated with cytochrome c biogenesis

Research in Microbiology, 2001
It is generally agreed that cytochrome c biogenesis requires that the apocytochrome and heme be transported separately to their site of function and assembly. In bacteria, this is outside the cytoplasmic membrane, whereby the apocytochromes c use sec-dependent signals for their translocation.

Cytochrome c Biogenesis

EcoSal Plus, 2008
Escherichia coli employs several c -type cytochromes, which are found in the periplasm or on the periplasmic side of the cytoplasmic membrane; they are used for respiration under different growth conditions. All E. coli c -type cytochromes are multiheme cytochromes;

Cytochrome c biogenesis in mitochondria

Mitochondrion, 2008
As part of the respiratory chain, c-type cytochromes are essential electron transporters. They are characterized by the covalent attachment of a heme prosthetic group. The biogenesis of these proteins includes all the processes leading to this fixation. Yeast and animals have evolved a comparatively simple mechanism relying on cytochrome c heme lyases.

Biogenesis of c-type Cytochromes and Cytochrome Complexes

2009
In most anoxygenic phototrophic bacteria, apocytochromes c are synthesized in the cytoplasm, translocated across the membrane and matured to holocytochromes c on the periplasmic side. The extracytoplasmic maturation process requires a complex biogenesis pathway (Ccm-system I) consisting of up to ten components to carry out specific steps. These include

Redox Processes Controlling the Biogenesis of c -Type Cytochromes

Antioxidants & Redox Signaling, 2010
In mitochondria, two mono heme c-type cytochromes are essential electron shuttles of the respiratory chain. They are characterized by the covalent attachment of their heme C to a CXXCH motif in the apoproteins. This post-translational modification occurs in the intermembrane space compartment.

Covalent cofactor attachment to proteins: cytochrome c biogenesis

Biochemical Society Transactions, 2005
Haem (Fe-protoporphyrin IX) is a cofactor found in a wide variety of proteins. It confers diverse functions, including electron transfer, the binding and sensing of gases, and many types of catalysis. The majority of cofactors are non-covalently attached to proteins.

Complexity and diversity in c-type cytochrome biogenesis systems

Biochemical Society Transactions, 2005
c-type cytochromes contain haem covalently attached to protein by thioether bonds formed post-translationally and requiring a dedicated biogenesis apparatus. Three biogenesis systems, found in different cell types, are well known. Here we discuss emerging evidence for at least one additional system, for unanticipated diversity in the location of the ...

Recombinant Biogenesis and Analysis of Cytochrome c Species

Recombinant expression and biogenesis of cytochrome c species is a simple and efficient method for the production of holocytochrome c species, thus presenting an avenue for the study of cytochrome c or the cytochrome c biogenesis pathways responsible for heme attachment. Here, we describe a method for recombinant E.
