WebJan 18, 2011 · Carrier proteins are four helix bundles of ∼80 amino acids, found either as isolated proteins or as domains in larger multi-domain proteins, such as polyketide … 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, superoxide is often produced with nitric oxide. In the presence of nitric oxide, the reduction of cytochrome c is inhibited. This leads to the oxidisation of cytochrome c to cyto…
