An engineered thermally tolerant apo-cytochrome scaffold for metal-less incorporation of heme derivative.

PLoS ONE, 2023
Cytochrome c552 from Thermus thermophilus is one of the hot topics for creating smart biomaterials as it possesses remarkable stability, is tolerant to multiple mutations and has therefore been recently reported for a number of functionalizations upon ...

Decoding the role of cytochrome c in metabolism of human spermatozoa by Raman imaging

Frontiers in Cell and Developmental Biology, 2022
The normal functioning of sperm cells requires cytochrome c in the redox balanced forms: reduced and oxidized. The oxidized form of cytochrome c is localized in the mitochondrial intermembrane space and is a part of the electron transport chain.

NMR Study on the Mechanism of Cytochrome c Methionine Oxidation

Chinese Journal of Magnetic Resonance, 2023
Mitochondria generate reactive oxygen species (ROS) during respiration. Low levels of ROS are conducive to signal transduction, whereas excessive accumulation of ROS can lead to protein oxidative modification.

Extracytoplasmic prosthetic group ligation to apoproteins: maturation of c‐type cytochromes [PDF]

Molecular Microbiology, 2006
SummaryIn all organisms, haem is post‐translationally and covalently attached to c apocytochromes to produce c holocytochromes via a process called c‐type cytochromes maturation, which involves numerous components. In bacteria it was not clear which of these components catalyses the extracytoplasmic haem–apocytochrome ligation per se.

Hypericin Enhances Paclitaxel-Induced B16-F10 Cell Apoptosis by Activating a Cytochrome c Release–Dependent Pathway

Frontiers in Pharmacology, 2021
The enhanced inhibitory effect of paclitaxel (PTX) combined with hypericin (HY) on B16-F10 cells may be realized through the ROS-related cytochrome c release pathway.

Heme-a, the heme prosthetic group of cytochrome c oxidase, is increased in Alzheimer's disease [PDF]

Neuroscience Letters, 2009
Heme-a, is the heme prosthetic group of cytochrome c oxidase (COX), the terminal complex of the mitochondrial electron transport chain. We measured heme-a levels in postmortem brain tissue from nine patients diagnosed with dementia: Alzheimer's disease (AD) was the primary diagnosis in five, AD/diffuse Lewy body disease (DLBD) was diagnosed in two ...

Is cytochrome c oxidase subunit I (COI) the right DNA barcoding marker for the Chaetopteryx villosa group? [PDF]

ARPHA Conference Abstracts, 2021
Chaetopteryx villosa (Fabricius, 1798) is a caddisfly species distributed throughout Europe, except in the Balkan and Apennine Peninsula. However, phylogenetically close species belonging to the C. villosa group are widespread throughout entire Europe. Species of this group (C. villosa, C. gessneri, C. fusca, C. sahlbergi, C. atlantica, C. bosniaca, C.
