Structural parameters derived from SAXS data

	R_g (Å) Guinier	R_g (Å) GNOM	D_max (Å)	MW^Pred (kDa)^a	MW^saxs (kDa)^b	χ / χ²_free
Post-cleavage	40.1 ± 0.5	40.2 ± 0.2	140 ± 5	128	–	1.01/1.51
Apo-Rnt1p	46.7 ± 0.8	45.9 ± 0.5	160 ± 5	108	106	0.34/0.12

The MW^pred was calculated from the primary sequences of components.

The MW^SAXS was calculated using the power-law relationship between a mass parameter, Q_R, and particle mass, empirically determined on the basis of SAXS data for a particular class of macromolecular particles. Due to the lack of SAXS data, such relationship remains undetermined for protein-nucleic acid complexes (Rambo and Tainer, 2013a).
