| Abstract: | The interaction of horse ferricytochrome c with the reagents Fe(EDTA)(H2O)]? and Cr(CN)6]3? were studied at pH 7 and 25°C by 1H-NMR spectroscopy. Two binding regions near to the heme crevice of cytochrome c were identified. Both regions bound both reagents but they exhibited different selectivities. The relevance of this finding to the electron-transfer function of cytochrome c is discussed. |
