Cytochrom c evolution
WebIn the early 1960s, a linear evolution of cytochromes was suggested by Emanuel Margoliash [7] that led to the molecular clock hypothesis. The apparently constant evolution rate of cytochromes can be a helpful tool in trying to determine when various organisms may have diverged from a common ancestor. [8] Types [ edit] Cytochrome c is a highly conserved protein across the spectrum of eukaryotic species, found in plants, animals, fungi, and many unicellular organisms. This, along with its small size (molecular weight about 12,000 daltons), makes it useful in studies of cladistics. Cytochrome c has been studied for the glimpse it … See more The cytochrome complex, or cyt c, is a small hemeprotein found loosely associated with the inner membrane of the mitochondrion where it plays a critical role in cellular respiration. It transfers electrons between See more Electron transport chain Cytochrome c is an essential component of the respiratory electron transport chain in mitochondria. The See more Superoxide detection Cytochrome c has been used to detect peroxide production in biological systems. As superoxide is produced, the number of oxidised cytochrome c increases, and reduced cytochrome c decreases. However, … See more Cytochrome c belongs to class I of the c-type cytochrome family and contains a characteristic CXXCH (cysteine-any-any-cysteine-histidine) amino acid motif that binds heme. This motif is located towards the N-terminus of the peptide chain and contains a histidine … See more Cytochrome c is widely believed to be localised solely in the mitochondrial intermembrane space under normal physiological … See more • Cytochrome c oxidase See more • Kumarswamy R, Chandna S (February 2009).
