Rcf1 Modulates Cytochrome c Oxidase Activity Especially Under Energy-Demanding Conditions [PDF]
Frontiers in Physiology, 2020 The mitochondrial respiratory chain is assembled into supercomplexes. Previously, two respiratory supercomplex-associated proteins, Rcf1 and Rcf2, were identified in Saccharomyces cerevisiae, which were initially suggested to mediate supercomplex ...

Accelerated Evolution of Cytochrome c in Higher Primates, and Regulation of the Reaction between Cytochrome c and Cytochrome Oxidase by Phosphorylation [PDF]
Cells, 2022 Cytochrome c (Cc) underwent accelerated evolution from the stem of the anthropoid primates to humans. Of the 11 amino acid changes that occurred from horse Cc to human Cc, five were at Cc residues near the binding site of the Cc:CcO complex. Single-point

Structural Insights into Mechanisms Underlying Mitochondrial and Bacterial Cytochrome c Synthases [PDF]
BiomoleculesMitochondrial holocytochrome c synthase (HCCS) is an essential protein in assembling cytochrome c (cyt c) of the electron transport system. HCCS binds heme and covalently attaches the two vinyls of heme to two cysteine thiols of the cyt c CXXCH motif ...

Cytochrome c Negatively Regulates NLRP3 Inflammasomes. [PDF]
PLoS ONE, 2016 The release of cytochrome c from the inner mitochondrial membrane, where it is anchored by caridolipin, triggers the formation of the Apaf-1 apoptosome. Cardiolipin also interacts with NLRP3 recruiting NLRP3 to mitochondria and facilitating inflammasome ...

Interspecies Variation in the Functional Consequences of Mutation of Cytochrome c. [PDF]
PLoS ONE, 2015 The naturally occurring human cytochrome c variant (G41S) is associated with a mild autosomal dominant thrombocytopenia (Thrombocytopenia Cargeeg) caused by dysregulation of platelet production.

New insight into the mechanism of mitochondrial cytochrome c function. [PDF]
PLoS ONE, 2017 We investigate functional role of the P76GTKMIFA83 fragment of the primary structure of cytochrome c. Based on the data obtained by the analysis of informational structure (ANIS), we propose a model of functioning of cytochrome c. According to this model,

Lysine-PEGylated Cytochrome C with Enhanced Shelf-Life Stability
Biosensors, 2022 Cytochrome c (Cyt-c), a small mitochondrial electron transport heme protein, has been employed in bioelectrochemical and therapeutic applications. However, its potential as both a biosensor and anticancer drug is significantly impaired due to poor long ...

Multiple Mechanisms Regulate Eukaryotic Cytochrome C Oxidase
Cells, 2021 Cytochrome c oxidase (COX), the rate-limiting enzyme of mitochondrial respiration, is regulated by various mechanisms. Its regulation by ATP (adenosine triphosphate) appears of particular importance, since it evolved early during evolution and is still ...
