Figure 1
(a) SANS profiles and (b) Guinier plots of the PbaB tetramer deuterated by 0% (open squares), 50% (filled circles), 75% (filled squares) and 100% (open circles). The straight lines show the results of the least-squares fitting using the Guinier formula. (c) Square root of zero-angle scattering intensity as a function of the degree of protein deuteration. The straight line is the best fit to the data and is obtained by linear least-squares fitting. The matching point is at 73.8% deuteration. |
