A novel pathway for cytochromes c biogenesis in chloroplasts
The cytochromes c are a useful model for the study of the pathways and mechanisms of assembly of the cofactor-containing components of energy transducing membranes. Genetic analyses have identified proteins that are required for the assembly of c-type cytochromes in mitochondria, bacteria and chloroplasts.

Protein markers of mitochondria formation and alteration in patients with impaired blood circulation
Patients with abnormal left ventricular outflow tract had middle lactic acidemia with detected cytochrome C release into the bloodstream and liberation of protein PGC1a (peroxisome proliferator-activated receptor gamma coactivator-1alpha) with elevation ...

Composition and function of cytochrome c biogenesis System II [PDF]
Organisms employ one of several different enzyme systems to mature cytochromes c. The biosynthetic process involves the periplasmic reduction of cysteine residues in the heme c attachment motif of the apocytochrome, transmembrane transport of heme b and stereospecific covalent heme attachment via thioether bonds. The biogenesis System II (or Ccs system)

Cytochrome c oxidases are members of the heme-copper oxidase superfamily. These enzymes have different subunits, cofactors, and primary electron acceptors, yet they all contain identical heme-copper (CuB) binuclear centers within their catalytic subunits.

Upregulation of Mitochondrial Content in Cytochrome c Oxidase Deficient Fibroblasts. [PDF]
Cytochrome-c-oxidase (COX) deficiency is a frequent cause of mitochondrial disease and is associated with a wide spectrum of clinical phenotypes. We studied mitochondrial function and biogenesis in fibroblasts derived from the Cohen (CDs) rat, an animal ...

Mycobacterium tuberculosis depends on aerobic respiration for growth and utilizes an aa3-type cytochrome c oxidase for terminal electron transfer. Cytochrome c maturation in bacteria requires covalent attachment of heme to apocytochrome c, which occurs ...
