The difficult chemistry of nitrous oxide (N2O) reduction to gaseous nitrogen (N2) in biology is catalysed by the novel micro4-sulphide-bridged tetranuclear Cuz cluster of the N2O reductases (N2OR). Two spectroscopically distinct forms of this cluster have been identified as CuZ and CuZ*. We have obtained a 1.86 A resolution crystal structure of the pink-purple species of N2OR from Achromobacter cycloclastes (AcN2OR) isolated under aerobic conditions. This structure reveals a previously… CONTINUE READING
