1
Molecular mass values were calculated from mass spectrometry data.
2
Predicted sedimentation coefficients for the linear crystal-derived models were calculated using HYDROPRO.
3
The first value was determined from Guinier Rg anlysis; the second value was determined from GNOM P(r) analysis.
4
The first and second values were obtained from Guinier Rg and GNOM P(r) analyses of the modelled I(Q) curves for linear (POG)6-(POG)12 crystal-derived structures. The same Q range was used for both experimental and modelled curves.
5
The R factors were calculated by comparing experimental I(Q) curves against modelled I(Q) curves for the linear crystal-derived structures.
