Figure 3. The static domain of Orb2A88 is dominated by residues found in the first 22 residues.

(A) The strongest cross peaks of the DREAM spectrum of Orb2A88 recorded at 25 kHz MAS and 0 °C belong to residues that are exclusive to or prevalent in the N-terminal 22 residues of Orb2A. Positive and negative signal is shown with blue and red contours, respectively. (B) The 2D DARR spectrum recorded under the same conditions shows additional cross peaks of residues such as Gln and His that are not found in the N-terminus. Only positive contours are shown.
