Abstract:
The 8Fe-8S ferredoxin from Clostridium pasteurianum was investigated by 1D and 2D 1H NMR. Spectra of a well-structured, full native preparation of the oxidized protein in 1 M NaCl at pH 8.0 are presented. Assignments of non-isotropically shifted resonances in the diamagnetic region of the spectrum, namely those of the unique aromatic residues F30 and Y2, are presented for the first time.
