Extended Data Fig. 6: Inter-residue correlations obtained from 250 ms 2D 13C spin diffusion spectra of ERGIC-membrane bound ETM.

a, Representative strips from a well-resolved 3D NCACX spectrum recorded with 250 ms 13C spin diffusion. Inter-residue cross peaks are assigned in black and intra-residue resonances are marked in blue. b, Overlay of 2D 13C-13C correlation spectra measured with 250 ms mixing (black) and 20 ms (orange). Representative inter-residue cross peaks are assigned in blue. All spectra were measured at 293 K under 11.8 kHz MAS.
