Table 2. Radii of gyration and maximum dimensions of crystallographic dimer, cryo-EM based model, SAXS data and Dadimodo model.

Radii of gyration and Dmax were calculated with Crysol for structural models, for which termini were included. P(R) analysis was used for experimental data.

	Radii of gyration (Å)	Dmax (Å)
SAXS GI.1	43.3	150
SAXS GIII.2	42.0	150
GI.I Xray	32.7	99.6
Cryo-EM Model	35.1	110.9
Dadimodo	43.7	202.1
