title: [Study on interaction between the metal ion in the active site of cytochrome C and trace elements by ultraviolet spectroscopy].
abstract: The direct interaction between the metal ion in the active center of cytochrome C(Fecyt-C) and four trace elements in pH 7.1 phosphate buffer by UV spectrometry has been studied. As a result, part of the metal ion Fe(II) in Fecyt-C was replaced and the corresponding cytochrome C derivatives were produced. The Soret absorption maximum is blue-shifted and the absorption coefficient of the alpha band relative to that of the beta band is decreased in comparison to the Fecyt-C.
