Function
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
Protein crystals with their precise, periodic array of functional building blocks have potential applications in biomaterials, sensing, and catalysis. This paper describes how a highly porous crystalline framework of a cationic redox protein and an anionic macrocycle can be modulated by a small cationic effector. Ternary composites of protein ( approximately 13 kDa), calix[8]arene ( approximately 1.5 kDa), and effector ( approximately 0.2 kDa) formed distinct crystalline architectures, dependent on the effector concentration and the crystallization technique. A combination of X-ray crystallography and density functional theory (DFT) calculations was used to decipher the framework variations, which appear to be dependent on a calixarene conformation change mediated by the effector. This "switch" calixarene was observed in three states, each of which is associated with a different interaction network. Two structures obtained by co-crystallization with the effector contained an additional protein "pillar", resulting in framework duplication and decreased porosity. These results suggest how protein assembly can be engineered by supramolecular host-guest interactions.
