Structural highlights 2hv4 is a 1 chain structure with sequence from Saccharomyces cerevisiae. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: Solution NMR, 35 models Ligands: Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT 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-protein interactions are driven by specific properties of the molecular surfaces. Cytochrome c, a small electron transfer protein, is involved in a number of biologically relevant interactions with macromolecular partners. Small molecules may interfere with such interactions by binding to the surface of cytochrome c. Here we investigated the possibility of weak intermolecular interactions between reduced cytochrome c and a library of 325 small molecules, using WaterLOGSY NMR spectroscopy. Specific binding was found for p-aminophenol. The solution structure of the p-aminophenol-cytochrome c adduct was determined using a combination of in silico tools and NMR-based restraints. The ligand interacts in a specific binding site on the protein surface through a combination of stacking and H-bond interactions. Small but meaningful rearrangements of the solvent-exposed side chains are observed upon ligand binding and contribute to the stabilization of the complex.
