Abstract excerpt

The geometries of the metal sites in cadmium-substituted azurins have been investigated by 111mCd perturbed angular correlation (PAC). The study includes wild type azurin as well as Met121 mutants of azurin, where methionine has been substituted by Ala, Asn, Asp, Gln, Glu, and Leu. The nuclear quadrupole interaction of wild type azurin analyzed in the angular overlap model is well described as coordination of...
