Spectroscopic, Computational and Kinetic Studies of the μ(4)-Sulfide Bridged Tetranuclear Cu(Z) Cluster in N(2)O Reductase: pH Effect on the Edge Ligand and its Contribution to Reactivity

A combination of spectroscopy and DFT calculations has been used to evaluate the pH effect at the Cu(Z) site in Pseudomonas nautica (Pn) N(2)OR and Achromobacter cycloclastes (Ac) N(2)OR and its relevance to catalysis. Absorption, MCD, EPR with sulfur K-edge XAS spectra of the enzymes at high and lo...
