“…The characteristics observed for the excited-state deactivation process occurring in POXC suggest that its T1 Cu site characteristics are different from those of the other proteins investigated by ultrafast resonant pump-probe spectroscopy. This well correlates with the hypothesis that POXC T1 Cu is strongly coordinated to only the three ligands constituting the common T1 Cu ligand set, i.e., thiolate sulfur of a cysteine residue and the imidazole nitrogens of two histidine residues, and thus T1 site features a trigonal geometry [3,10,28]. In fact in all of the copper-containing proteins so far investigated by ultrafast resonant pump-probe spectroscopy the T1 copper is ligated to at least four ligands.…”

“…(3,(10)(11)(12)(13) First, the spectral features resulting from the d9 oxidized blue Cu ground state wavefunction are well understood. (3,10) This half-occupied orbital participates in electron transfer which is facilitated by a high degree of covalency anisotropically distributed along one Cu-ligand bond (the cysteine).…”
