Engineered protein active site designed by Borovik and coworkers and crystallographic determination at 1.62 Å resolution.721 Multiple H-bonding interactions are observed with the hydroperoxide moiety in the CuII–OOH structure: 01···03 = 3.2 Å and 04···Ν(Ν49) = 3.0 Å. Further, Cu–O3 = 1.9 Å; O3–O4 = 1.5 Å; and Cu–O2 = 2.6 Å.
