Figure 1. [¹H, ¹⁵N] TROSY-HSQC spectra of the human Hsp90 N-terminal domain in its (a) free, (b) AMPPCP- and (c) ADP-bound states.

Backbone amide resonance assignments are labeled with one-letter amino acid code and sequence number. Grey dots indicate resonances which are invisible at the current contour level. Regions with cross-peaks partially overlapped are zoomed in.
