Biogenesis of Cytochrome c in Neurospora crassa [PDF]

, 1978
# 1. Precipitating antibodies specific for apocytochrome c and holocytochrome c, respectively, were employed to study synthesis and intracellular transport of cytochrome c in Neurospora in vitro. # 2.

HEME Trafficking by the Cytochrome C Biogenesis Pathways [PDF]

Biophysical Journal, 2017
Cytochromes function in electron transport chains to perform critical cellular functions, such as respiration and photosynthesis. Cytochromes c are unique due to their requirement for the covalent attachment of heme via two thioether bonds at a conserved CXXCH motif. Three pathways have been identified for cytochrome c maturation: System I (prokaryotes)

Mitochondrial cytochrome c biogenesis: no longer an enigma [PDF]

Trends in Biochemical Sciences, 2015
Cytochromes c (cyt c) and c1 are heme proteins that are essential for aerobic respiration. Release of cyt c from mitochondria is an important signal in apoptosis initiation. Biogenesis of c-type cytochromes involves covalent attachment of heme to two cysteines (at a conserved CXXCH sequence) in the apocytochrome.

Continued surprises in the cytochrome c biogenesis story [PDF]

Protein & Cell, 2012
Cytochromes c covalently bind their heme prosthetic groups through thioether bonds between the vinyl groups of the heme and the thiols of a CXXCH motif within the protein. In Gram-negative bacteria, this process is catalyzed by the Ccm (cytochrome c maturation) proteins, also called System I.

Structure-Function Analysis of the Bifunctional CcsBA Heme Exporter and Cytochrome c Synthetase

mBio, 2018
Although intracellular heme trafficking must occur for heme protein assembly, only a few heme transporters have been unequivocally discovered and nothing is known about their structure or mechanisms.

Biogenesis of mitochondrialc-type cytochromes

Journal of Bioenergetics and Biomembranes, 1990
Cytochromes c and c1 are essential components of the mitochondrial respiratory chain. In both cytochromes the heme group is covalently linked to the polypeptide chain via thioether bridges. The location of the two cytochromes is in the intermembrane space; cytochrome c is loosely attached to the surface of the inner mitochondrial membrane, whereas ...

Yeast cytochrome c oxidase: a model system to study mitochondrial forms of the haem-copper oxidase superfamily. [PDF]

, 2012
The known subunits of yeast mitochondrial cytochrome c oxidase are reviewed. The structures of all eleven of its subunits are explored by building homology models based on the published structures of the homologous bovine subunits and similarities and ...

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

Hepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Biogenesis of eukaryotic cytochrome c oxidase

Physiological Research, 2006
Eukaryotic cytochrome c oxidase (CcO), the terminal component of the mitochondrial electron transport chain is a heterooligomeric complex that belongs to the superfamily of heme-copper containing terminal oxidases. The enzyme, composed of both mitochondrially and nuclear encoded subunits, is embedded in the inner mitochondrial membrane, where it ...
