In this work, we used the previously inserted ATCUN motif in the Desulfovibrio gigas orange protein (ORP) to increase our understanding of the molybdenum/copper heterometallic cluster (Mo/Cu) assembly in ORP. A detailed mechanism of the formation of the ORP Mo/Cu cluster is discussed, suggesting that CuII is reduced to CuI and transferred from the ATCUN site to the cluster-binding region upon the interaction of two ORP molecules.
