Figure 5: Chain dynamics in HIV-1-PR1-95 .in denaturant conditions . NMR relaxation rates (a-c) and
spectral densities (d-f) in 25% acetic acid (blue dots), in 8M urea
(red dots), in 4M urea (orange dots), in 0.9M GdmCl (green dots) and in
buffer at 5 °C (black dots). Secondary structures of folded HIV-1-PR1-95 are shown in the top.
