Nitrous-oxide reductases (N2OR) catalyze the two-electron reduction of N(2)O to N(2). The crystal structure of N2ORs from Pseudomonas nautica (Pn) and Paracoccus denitrificans (Pd) were solved at resolutions of 2.4 and 1.6 A, respectively. The Pn N2OR structure revealed that the catalytic CuZ center belongs to a new type of metal cluster in which four copper ions are liganded by seven histidine residues. A bridging oxygen moiety and two other hydroxide ligands were proposed to complete the… CONTINUE READING
