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 ...

Complexation of CcmB with CcmACD safeguards heme translocation for cytochrome c maturation [PDF]
mLifeCytochrome c maturation (CCM), a posttranslational modification involving covalent attachment of heme to polypeptides (apocyt c), is essential for the activity and cellular function of cytochromes c.

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.

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 ...

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 ...

Nitrogen-Vacancy Magnetic Relaxometry of Nanoclustered Cytochrome C Proteins [PDF]
Nano Letters 24, 3, 873-880, 2024, 2023 Nitrogen-vacancy (NV) magnetometry offers an alternative tool to detect paramagnetic centers in cells with a favorable combination of magnetic sensitivity and spatial resolution. Here, we employ NV magnetic relaxometry to detect cytochrome C (Cyt-C) nanoclusters.
