Bioinorganic enzyme-based

Copper proteins. EPR spectroscopy has played an important role in determining structural and redox properties in Cu-containing enzymes. Based on the spectra of bioinorganic model compounds, it became possible to determine the symmetry and coordination environment of many Cu-containing proteins from the EPR spectra. Correlations between EPR and optical spectra also provided important guides to determining the structures and ligands and led to the discovery of two distinct types of... [Pg.532]

Bioinorganic chemists have been attracted by the complex formations of NHC because the imidazolin-2-ylidene motif is encountered frequently in living organisms. The imidazole moiety is part of the purin bases in both DNA and RNA as well as the amino acid histidine which appears in proteins and enzymes and is in many cases considered to play a decisive role within the catalytically active center. The possible formation of NHC complexes under physiological conditions or in vivo has been addressed by investigation of A-confused caffeine 73 or purine 74 complexes. [Pg.56]
