摘要

Pseudoazurin (PAz) from Achromobacter cycloclastes functions as an electron donor to nitrite reductase and nitrous oxide reductase. The copper atom is coordinated by His40 and His81 imidazole N atoms of, Cys78 thiolate S atom, and Met86 sulfide S atom with distorted tetrahedral geometry. The Met16 residue is located in the vicinity of His81 and weakly interacted to the active site [1], and several Met16 mutated PAz were studied to shed light on the role of weak interaction on the electronic structure of blue copper protein.
