WebAug 22, 2005 · For a given protein, folding routes largely depend on the protein's stability and its native-state geometry, because the landscape is funneled. These ideas are corroborated for cytochrome c by using a coarse-grained topology-based model with a perfect funnel landscape that includes explicit modeling of the heme. WebCu is found in the structure of many enzymes like cytochrome C, which is involved in the respiratory chain reaction and mitochondrial energy production, metallothioneins, and CuZn-SOD structure, which has antioxidative function. Involvement of Cu deficiency in the teratogenicity has been postulated [146 ].
