WebOct 25, 2008 · In the course of the structure determination of the bc 1 complex from R. sphaeroides, we observed that the growth of only low quality crystals correlated with low activity and stability of the purified complex, which was mitigated in part by introducing a double mutations to the enzyme. Cytochrome b is commonly used as a region of mitochondrial DNA for determining phylogenetic relationships between organisms, due to its sequence variability. It is considered to be most useful in determining relationships within families and genera. Comparative studies involving cytochrome b have resulted in new classification schemes and have been used to assign newly described species to a genus as well as to deepen the understanding of evolutionary relationships. citycol loja onlineWebMar 6, 2024 · Cytochrome c (Figure 5.47) is a soluble protein loosely associated with the mitochondrion.
