The atomic dynamics of the enzyme Cu/Zn superoxide dismutase hydrated to 0.34g D2O/g protein has been investigated by means of inelastic neutron scattering at different temperatures between 50 and 300 K. At all temperatures the inelastic part of the spectrum is well separated from the quasi-elastic region. The vibrational frequency distribution function G(w) shows, for all temperatures, a Debye-like behaviour up to about 5 meV.

Abstract

The atomic dynamics of the enzyme Cu/Zn superoxide dismutase hydrated to 0.34g D2O/g protein has been investigated by means of inelastic neutron scattering at different temperatures between 50 and 300 K. At all temperatures the inelastic part of the spectrum is well separated from the quasi-elastic region. The vibrational frequency distribution function G(w) shows, for all temperatures, a Debye-like behaviour up to about 5 meV.
