The electronic properties of Thermus thermophilus Cu(A) in the oxidized form were studied by (1)H and (13)C NMR spectroscopy. All of the (1)H and (13)C resonances from cysteine and imidazole ligands were observed and assigned in a sequence-specific fashion. The detection of net electron spin density on a peptide moiety is attributed to the presence of a H-bond to a coordinating sulfur atom. This hydrogen bond is conserved in all natural Cu(A) variants and plays an important role for maintaining ...[more]
