Figure 7

Amide proton R1ρ relaxation data on WT ubiquitin and comparison to 15N R1ρ rate constants. Top panel: 1H R1ρ obtained at a 1H Larmor frequency of 950 MHz, using a deuterated sample of MPD-ub in which 70% of the exchangeable sites were reprotonated, and a MAS frequency of 54 kHz. Middle panel: 15N R1ρ rate constants reported earlier [45], using a deuterated, 50% reprotonated sample at 600 MHz and 39.5 kHz MAS. Lower panel: correlation of these two data sets; a linear regression curve is shown (slope: 0.15, intercept: -1.35s -1, correlation coefficient 0.80).
