Solid-state NMR dipolar order parameters for the (¹³C¹H)β (black; filled circles) and (¹³C¹H₂)β (red; open circles) spin systems in uniformly labeled Pf1 coat protein, presented as described in Fig. 1 for Cα values. The Cβ sites have a large dynamic range, and many sites are static, including a few ¹³C¹H₂ sites.
