Abstract

Abstract We have measured the oxidation-reduction potential of parsley ferredoxin and its derivative in which the two atoms of labile sulfide have been replaced by selenide. The values are –0.416 V (25°, pH 7.94) and –0.378 V (25°, pH 8.14) for the sulfur and selenium derivatives, respectively. Both values show a slight negative dependence on pH.
