Size parameters determined from SAXS data.

aRadius of gyration calculated from the SAXS data by using the Guinier approximation or AUTOGNOM. Error estimates are the standard error of the linear regression and standard deviation, respectively.bDmax values estimated by using the indirect transform program AUTOGNOM.cMolecular weight calculated from protein and RNA sequence.dMolecular weight calculated from SAXS data by comparison with the protein standard bovine serum albumin. Error estimates are for propagation of standard error calculated for I(0)/c from linear regression, where I(0) is the forward scattering intensity and c is the concentration of protein in g/l.Size parameters determined from SAXS data.
