- Abstract:
-
15N NOE, T1, and T2 measurements have been carried out on uniformly 15N-labeled human interleukin-4. Analysis of the results in terms of order parameters (S2) shows that although the helical core of this four-helix-bundle protein exists as a well-defined structure with limited conformational flexibility (S2 congruent to 0.9), other regions of the molecule experience substantial fluctuations in the conformation of the main chain (S2 = 0.3-0.8). These regions include both the N- and C-termini a...
