Efficient and selective isotopic labeling of hemes to facilitate the study of multiheme proteins

BioTechniques, 2012
Specific isotopic labeling of hemes provides a unique opportunity to characterize the structure and function of heme-proteins. Unfortunately, current methods do not allow efficient labeling in high yields of multiheme cytochromes c, which are of great ...

Iron or sulfur respiration—an adaptive choice determining the fitness of a natronophilic bacterium Dethiobacter alkaliphilus in geochemically contrasting environments

Frontiers in Microbiology, 2023
Haloalkaliphilic microorganisms are double extremophiles functioning optimally at high salinity and pH. Their typical habitats are soda lakes, geologically ancient yet widespread ecosystems supposed to harbor relict microbial communities.

The heme auxotroph Caenorhabditis elegans can cleave the thioether bonds of c-type cytochromes [PDF]

, 2018
Heme is essential and synthesised via highly-regulated processes. For this reason, most organisms strive to recycle it or acquire it from their environment.

Deep-branching ANME-1c archaea grow at the upper temperature limit of anaerobic oxidation of methane

Frontiers in Microbiology, 2022
In seafloor sediments, the anaerobic oxidation of methane (AOM) consumes most of the methane formed in anoxic layers, preventing this greenhouse gas from reaching the water column and finally the atmosphere.

The complex of cytochrome c and cytochrome c peroxidase: The end of the road?

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2011
Cytochrome c (Cc) and cytochrome c peroxidase (CcP) form a physiological complex in the inter-membrane space of yeast mitochondria, where CcP reduces hydrogen peroxide to water using the electrons provided by ferrous Cc. The Cc-CcP system has been a popular choice of study of interprotein biological electron transfer (ET) and in understanding dynamics ...

Evolution of the Couple Cytochrome c and Cytochrome c Oxidase in Primates [PDF]

, 2012
Mitochondrial energy metabolism has been affected by a broad set of ancient and recent evolutionary events. The oldest example is the endosymbiosis theory that led to mitochondria and a recently proposed example is adaptation to cold climate by anatomically modern human lineages.

Cytochromes c of Campylobacter sputorum subspecies mucosalis [PDF]

, 1982
Campylobacter sputorum subspecies mucosalis, the causative organism of porcine intestinal adenomatosis, will grow microaerophillically in the presence of hydrogen as an electron donor, and under these conditions contains a high complement of c-type ...

Optimizing Electroactive Organisms: The Effect of Orthologous Proteins

Frontiers in Energy Research, 2019
Extracellular electron transfer pathways allow bacteria to transfer electrons from the cell metabolism to extracellular substrates, such as metal oxides in natural environments and electrodes in microbial electrochemical technologies (MET).

Detection of c-type cytochromes using enhanced chemiluminescence

, 1993
A rapid, nontoxic method was devised for staining c-type cytochromes on filters. Bacterial and mitochondrial c-type cytochromes from sodium dodecylsulfate-polyacrylamide gels were transferred to nitrocellulose filters and visualized by a staining system ...
