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

under some conditions, electron transfer may be rate limiting in N2O reduction. The transition state is stabilized by H-bonding interactions between the active site and an N2O-derived intermediate bound to the catalytic CuZ cluster

Marinobacter nauticus
-
the purple form of enzyme, in which the copper centre is in the oxidized [2Cu2+:2Cu+] redox state, is redox active, although it is still catalytically non-competent, as its specific activity is lower than that of the activated fully reduced enzyme and comparable with that of the enzyme with the copper centre in either the [1Cu2+:3Cu+] redox state or in the redox inactive state
