The influence of amino acid side chains on water binding to the copper(II) in bis(N,N-dimethyl-L-alpha-isoleucinato)-copper(II): an EPR and molecular mechanics study.
Simulations were done of the electron paramagnetic resonance (EPR) spectra for bis(N,N-dimethyl-L-alpha-isoleucinato)copper(II) dissolved in deuterated methanol as a function of temperature. They indicated different behaviour of the complex below and above 300 degrees K. The effect was examined by the conformational analysis of the copper(II) complex with a new molecular mechanics force field.
