Low temperature absorption, circular dichroism, and magnetic circular dichroism spectral studies of the blue copper proteins Rhus vernicifera stellacyanin, bean plastocyanin, and Pseudomonas aeruginosa azurin have been made. Low energy bands attributable to the d-d transitions 2B2 leads to 2E and 2B2 leads to 2B1 in a flattened tetrahedral (D 2d) copper-(II) center are observed in these protein...
