FIG. 5.
Squares of the generalized order parameters by a model-free analysis of internal motions, S2, of the Tva LDL-A module (A) and LRP CR8 (B). For the Tva LDL-A module, relaxation parameters were determined for 37 nonproline residues. The remaining four nonproline residues could not be determined due to spectrum overlapping or a weak signal. For LRP CR8, relaxation parameters were determined for 42 nonproline residues. Note that the residues at the N and C termini of the recombinant Tva module are derived from the vector and are designated − or +, respectively. The residues for CR8 are numbered as described by Huang et al. (18). Bar, residues between the second and the third cysteines of Tva with a low S2 value.
