Abstract:Finally efforts towards the design of a biosynthetic model of Cu Z from N2OR are reported. The CuZ cluster is the first and only report to date of a copper-sulfide cluster in Nature. It fulfills a catalytic role in N2OR, performing the reduction of N2O to N2 and H2O during anaerobic respiration, with reducing equivalents provided by a CuA site. The cluster is composed of four copper atoms bridged by a central sulfide, with remaining all histidine coordination to the copper atoms. A scaffold protein was selected, and residues were chosen for mutagenesis to create a similar ligand set to CuZ in N2OR. The copper binding properties and copper/sulfide binding properties of the biosynthetic and native N2OR systems were investigated towards efforts to reconstitute them.
