Cytochrome c is an essential component of the respiratory electron transport chain in mitochondria. The heme group of cytochrome c accepts electrons from the bc 1 Complex III and transports them to Complex IV, while it transfers energy in the opposite direction.
Cytochrome c is a peripheral protein of the mitochondrial inner membrane and functions as an electron shuttle between complex III and complex IV of the respiratory chain and its activity is necessary for life.
Cytochrome c is primarily known for its function in the mitochondria as a key participant in the life-supporting function of ATP synthesis.
Cytochrome c is an important component of the Electron Transport Chain for the synthesis of ATP (Figure 2). Cytochrome c is a water soluble electron transport protein that is loosely associated with the mitochondrial inner membrane.
In healthy cells, cytochrome c (Cyt c) is located in the mitochondrial intermembrane/intercristae spaces, where it functions as an electron shuttle in the respiratory chain and interacts with...
The redox-active protein cytochrome c is a highly positively charged hemoglobin that regulates cell fate decisions of life and death.
Cytochrome c is primarily known for its function in the mitochondria as a key participant in the life-supporting function of ATP synthesis. However, when a cell receives an apoptotic stimulus, cytochrome c is released into the cytosol and triggers programmed cell death through apoptosis.
Cytochrome c with heme c. Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in the electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding.
Cytochrome c, a protein that belongs to class 1 of the c-type cytochrome family, exerts different functions depending on its cellular localization and the conditions in which it operates; therefore, it can be defined as 'extreme multifunctional' protein.
Cytochrome c, shown here from PDB entry 3cyt , is a carrier of electrons. Like many proteins that carry electrons, it contains a special prosthetic group that handles the slippery electrons. Cytochrome c contains a heme group with an iron ion gripped tightly inside, colored red here. The iron ion readily accepts and releases an electron.
