New insight into the mechanism of mitochondrial cytochrome c function. [PDF]
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,

Oxidative stress is tightly regulated by cytochrome c phosphorylation and respirasome factors in mitochondria [PDF]
Respiratory cytochrome c has been found to be phosphorylated at tyrosine 97 in the postischemic brain upon neuroprotective insulin treatment, but how such posttranslational modification affects mitochondrial metabolism is unclear.

Structural Insights into Mechanisms Underlying Mitochondrial and Bacterial Cytochrome c Synthases [PDF]
Mitochondrial 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 ...

Import of cytochrome c into mitochondria [PDF]
The import of cytochrome c into mitochondria can be resolved into a number of discrete steps. Here we report on the covalent attachment of heme to apocytochrome c by the enzyme cytochrome c heme lyase in mitochondria from Neurospora crassa. A new method

Cytochrome c signalosome in mitochondria [PDF]
Cytochrome c delicately tilts the balance between cell life (respiration) and cell death (apoptosis). Whereas cell life is governed by transient electron transfer interactions of cytochrome c inside the mitochondria, the cytoplasmic adducts of cytochrome

Complexation of CcmB with CcmACD safeguards heme translocation for cytochrome c maturation [PDF]
Cytochrome 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.

Release of Cytochrome C from Bax Pores at the Mitochondrial Membrane
How cytochrome C is released from the mitochondria to the cytosol via Bax oligomeric pores, a process which is required for apoptosis, is still a mystery.

Biochemical mapping reveals a conserved heme transport mechanism via CcmCD in System I bacterial cytochrome c biogenesis [PDF]
Heme is a redox-active cofactor for essential processes across all domains of life. Heme’s redox capabilities are responsible for its biological significance but also make it highly cytotoxic, requiring tight intracellular regulation.

Cytochrome c Negatively Regulates NLRP3 Inflammasomes. [PDF]
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 ...
