STRUCTURE OF RICE FERRICYTOCHROME C AT 2.0 ANGSTROMS RESOLUTIONSTRUCTURE OF RICE FERRICYTOCHROME C AT 2.0 ANGSTROMS RESOLUTION
Structural highlights
Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of ferricytochrome c from rice embryos has been solved by X-ray diffraction to a resolution of 2.0 A, applying a single isomorphous replacement method with anomalous scattering effects. The initial molecular model was built on a graphics display system and was refined by the Hendrickson and Konnert method. The R factor was reduced to 0.25. Rice cytochrome c consists of III amino acid residues. In comparison with animal cytochromes c, the peptide chain extends for eight residues at the N-terminal end, which is characteristic for plant cytochromes c. These additional residues display a collagen-like conformation and an irregular reverse turn, and are located around the C-terminal alpha-helix on the surface or the rear side of the molecule. Two hydrogen bonds between the carbonyl oxygen of the N-terminal acetyl group and O eta of Tyr65, and between the peptide carbonyl oxygen of Pro-1 and O epsilon 1 of Gln89, are involved in holding these eight residues on the molecular surface, where Tyr65 and Gln89 are invariant in plant cytochromes c. Except for the extra eight residues, the main-chain conformations of both rice and tuna cytochromes c are essentially identical, though small local conformational differences are found at residues 24, 25, 56 and 57.
