Experimental and modelling SAXS parameters.

aValues for I(0) have been extrapolated by the Guinier approximation from the experimental scattering profiles.bConcentration of the protein used for the calculation of the estimated Mw.cRelative molecular mass estimated from I(0) and the concentration of the protein through BSA calibration.dThe Porod volume was calculated using PRIMUS [41].eExpected molecular mass predicted from the sequence and assuming full occupation of the glycosylation sites.fRg (Guinier), Rg (GNOM), radius of gyration given by the Guinier approximation, and calculated by the program GNOM, respectively, given in nm.gMaximum dimension of the macromolecules. χ2(over) Discrepancy between the SAXS profile and its fit by the overall shapes-models calculated by DAMMIF, and χ2 (sasref) the average discrepancy of the best atomic models estimated with the program CRYSOL.
