Figure 3

Comparisons of NMR spectra between the capsids from CFPS and capsids purified from E. coli. (A) Overlay of the 2D hHN spectra of the protonated Cp183 capsids from CFPS (in blue) and purified from E. coli (in gray); (B) overlay of the 2D planes from the 3D hCANH spectrum recorded on the protonated Cp183 CFPS capsids; (C) 2D hNH spectrum of the deuterated Cp183 CFPS capsids; (D) overlay of the 2D hNH spectra of the deuterated capsids from CFPS (in purple) and purified from E. coli (in orange), with resonances not observed in the E. coli sample highlighted as black circles. Spectra are shown individually in Figure S1. (E) Comparison of signal-to-noise ratios of the different samples; (F) comparison of proton linewidths in the different samples. The averages over the two protonated and the two deuterated samples are indicated.
