[[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.

Controlled protein assembly provides a means to generate biomaterials. Synthetic macrocycles such as the water-soluble sulfonato-calix[n]arenes are useful mediators of protein assembly. Sulfonato-thiacalix[4]arene (tsclx 4 ), with its metal-binding capacity, affords the potential for simultaneous macrocycle- and metal-mediated protein assembly. Here, we describe the tsclx 4 -/Zn-directed assembly of two proteins: cationic alpha-helical cytochrome c (cyt c) and neutral beta-propeller Ralstonia solanacearum lectin (RSL). Two co-crystal forms were obtained with cyt c, each involving multinuclear zinc sites supported by the cone conformation of tsclx 4 . The tsclx 4 /Zn cluster acted as an assembly node via both lysine encapsulation and metal-mediated protein-protein contacts. In the case of RSL, tsclx 4 adopted the 1,2-alternate conformation and supported a dinuclear zinc site with concomitant encapsulation and metal-binding of two histidine side chains. These results, together with the knowledge of thiacalixarene/metal nanoclusters, suggest promising applications for thiacalixarenes in biomaterials and MOF fabrication.
