The SAXS model: (a) The pair distribution function of the SAXS data determined during data reduction with GNOM [26]. (b) The agreement of the most probable DAMMIN [25] model of MjCorA (χ = 0.63); raw data are plotted as the natural logarithm of I + σ(I)/I(▾) and I − σ(I)/I(▴) against the scattering vector 1/S (Å^− 1), the model gives the calculated scattering curve shown in red. (c) Top (cytoplasmic) and side (d) views of an envelope representation of the DAMMIN model of MjCorA. Envelopes are rendered using the program UCSF Chimera [34] with the contour level calculated to enclose a volume corresponding to a mass of 272 kDa, accompanying scale bars are 25 Å long.
