| Figure 5 SAXS analysis of human FXIIHC5. (a) SEC-SAXS signal plot. Each point represents the integrated area of the ratio of the sample SAXS curve to the estimated background. The frames used as the buffer background are in grey with the average represented as a grey horizontal line. (b) Guinier plot. (c) Distance distribution function fit to the data with rescaled errors. (d) Distance distribution. (e) Kratky plot. The plots in (b)–(e) are taken from BayesApp. Fit of the interlocking dimeric crystal structure (f) into the 32 Å density envelope obtained from DENSS. (g) Comparison of the experimental SAXS curve (circles) with the curve calculated from the crystal monomeric (red) and dimeric (blue) structure models for data covering a momentum-transfer range of 0.0045 < q < 0.15 Å−1. The goodness-of-fit parameter from FoXS (χ2) is 1.78 for the monomer, with Rg = 25.54 Å, c1 = 0.99 and c2 = 3.23, and 4.75 for the dimer, with Rg = 26.95 Å, c1 = 1.05 and c2 = −2.00. |
