[https://www.uniprot.org/uniprot/CYC1_YEAST CYC1_YEAST] Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain.

== Publication Abstract from PubMed ==

In the general view of protein-complex formation, a transient and dynamic encounter complex proceeds to form a more stable, well-defined, and active form. In weak protein complexes, however, the encounter state can represent a significant population of the complex. The redox proteins adrenodoxin (Adx) and cytochrome c (C c) associate to form such a weak and short-lived complex, which is nevertheless active in electron transfer. To study the conformational freedom within the protein complex, the native complex has been compared to a cross-linked counterpart by using solution scattering and NMR spectroscopy. Oligomerization behavior of the native complex in solution revealed by small-angle X-ray scattering indicates a stochastic nature of complex formation. For the cross-linked complex, interprotein paramagnetic effects are observed, whereas for the native complex, extensive averaging occurs, consistent with multiple orientations of the proteins within the complex. Simulations show that C c samples about half of the surface area of adrenodoxin. It is concluded that the complex of Adx/C c is entirely dynamic and can be considered as a pure encounter complex.
