Figure EV2. 2D 1H‐15N Heteronuclear Single Quantum Correlation (HSQC) spectra of FGF21 (blue) and FGF21core (red).
Backbone amide resonance assignments were indicated with one‐letter amino acid code and sequence number. Arrows indicate the peak shifts upon the truncation of N‐ and C‐termini in FGF21core.
