Abstract
We have studied the collective dynamics of an hydrated soluble protein, the C-phycocyanin by using neutron spin-echo spectroscopy. Molecular dynamics simulations, performed with the same system, showed that the main dynamic c ontribution comes from backbone and side-chain motions. Both the experiment al and spectra exhibit a dynamic relaxation with a characteristic time of a bout 10 ps. (C) 2000 Elsevier Science B.V. All rights reserved.
