abstract

  • The identification of the spin systems that comprise the 1H nuclear magnetic resonance spectrum of French bean Cu(I) plastocyanin (Mr 10,600) has been made using an approach that integrates a wide range of two-dimensional nuclear magnetic resonance experiments. A very large percentage of these assignments has been obtained in spectra acquired from 1H2O solution using a backbone amide-based strategy. The spin systems of 91 of the 99 residues have been assigned to the appropriate amino acid, thereby providing an ample basis for obtaining sequence-specific assignments, as described in the accompanying paper.
