GLASSYLIKE LOW-FREQUENCY DYNAMICS OF GLOBULAR-PROTEINS

It is shown that globular proteins display a universal average structu re factor accounting for their common aminoacid base. This property, l inked to the construction of a random elastic network to study the low -frequency dynamics, leads to striking similarities between the physic s of globular proteins and that of glassy or amorphous nanocrystals. A few consequences of this interpretation are inquired into, particular ly, in connection with some of the universal properties of the low-fre quency dynamics that were recently discovered for globular proteins.
