Figure 2.

The dynamic region of NM is localized to the M domain. (a) The aliphatic region of the 1D INEPT spectrum of NM in the weak fiber form has multiple strong peaks with chemical shifts characteristic of the indicated amino acid atom types. These peaks are largely absent from (b) the CP spectrum of the weak fiber form. (c) The primary sequence of NM. Colored amino acids are those visible in the INEPT spectra, with red amino acids present only in the M domain. (see also Figure S1)
