title: Preparation of a covalently linked adduct between plastocyanin and cytochrome f.
abstract: Plastocyanin can be covalently cross-linked to the monomeric cytochrome f from turnip by incubation in the presence of a water-soluble carbodiimide. The adduct between the two proteins has a molecular weight of approximately 43,000 suggesting a 1:1 stoichiometry between the two proteins of the adduct. This stoichiometry has been verified by spectral characterization of the adduct. The efficiency of the cross-linking reaction is pH dependent with a higher degree of cross-linking being observed at pH 6.5 than at pH 7.0.
