FIGURE 7.

Mobility predictions for TePix(GAF) assembled with PVB in the Pb (blue) and Pg states (green). Plots show the experimental ¹⁵N backbone amide relaxation parameters versus the residue number determined by NMR spectroscopy at 600 Mhz. Data include longitudinal relaxation time (T₁), transverse relaxation time (T₂), and the steady-state ¹H,¹⁵N NOEs. The positions of the α-helices and β-strands are indicated above the panels. The magenta open circles indicate non-proline, non-termini residues for which the amides could not be assigned, and the black open circles indicate residues that were excluded from the amide dynamics analysis due to signal overlap or low signal to noise. Arrows locate the positions of Cys-494 and Cys-522 that form thioether bonds with the bilin. het, heteronuclear.
