blue copper electron-transfer protein pseudoazurin is capable of mediating electron transfer to the nitrous oxide reductase. Pseudoazurin binds near copper site CuA, with parameters consistent with the formation of a transient, weakly-bound complex. Pseudoazurin a strong candidate for the physiological electron donor to th enzyme
