  • Abstract According to the model free approach
    assumption four protein dynamic related parameters, the slow
    and fast local motion of the NH vector, the generalized order
    parameter, and the 15N shielding anisotropy can be
    estimated at each residue by the spectral density functions at the
    resonant frequencies of N (omega_N) and H (omega_H). In
    this work, we study the linear and nonlinear estimations of the
    aforementioned parameters of the two proteins C12A-p8^MTCPI
    and Pilin from strain K122-4. The principal components of the
    four parameters of C12A-p8^MTCPI are used to cluster the residues. The
    results show that the principle components provide useful
    information about the secondary structure of the protein.
    Finally, we propose a practical method to examine the model free
    assumption by characterizing the distribution of the transverse
    rate R_2 in multifield.
