Abstract
Protein function often depends on global, collective internal motions. However, the simultaneous quantitative experimental determination of the forms, amplitudes and timescale of these motions has remained elusive. Here, we demonstrate that a complete description of these large-scale dynamic modes can be obtained using coherent neutron scattering experiments on perdeuterated samples. Using this approach, a microscopic relationship between the structure, dynamics and function in a protein, cytochrome P450cam, is established. The approach developed here should be of general applicability to protein systems.Citation
