Oxidation-reduction properties of the regulatory site of spinach phosphoribulokinase.

Archives of biochemistry and biophysics - 1 Feb 1998

Hirasawa M, Brandes H K, Hartman F C, Knaff D B

Abstract excerpt

The oxidation-reduction midpoint potential (Em) of the regulatory disulfide, formed between Cys16 and Cys55, of spinach chloroplast phosphoribulokinase has been determined both for the wild-type enzyme and for a C244S-C250S double mutant, using enzymatic activity to monitor the oxidation-reduction state of the regulatory disulfide. At pH 7.0, Em values for the two-electron reduction of the regulatory disulfide of...
