    • The cupric geometry of blue copper proteins is not strained
    • of special interest. This paper presents ab initio quantum chemical calculations on an active site model for blue copper proteins, using both density functional theory and multirefence perturbation theory methods, and concludes that the active site geometry around the copper center is not strained. The use of multireference perturbation theory, a highly accurate quantum chemical method, on a reasonable size active site model, is particularly noteworthy here.

Here, QM structures (computed at the Hartree - Fock level) along the reaction path are docked into the active site and the energies are evaluated via a mixed QM/MM Hamiltonian. This is yet another approach to deploying QM/MM technology, and leads to reasonable qualitative agreement with experiments in terms of the ability of the enzyme to lower the barrier to reaction.
