Figure 4. Distance distribution function P(r) analyses for SCR-1/5 and SCR-16/20. (a) For SCR-1/5, M represents the most frequent distance within the protein and is 3.5 nm at 0.21 mg/ml, and L represents its maximum dimension at 15 nm. (b) For SCR-16/20 at lower concentrations, M rises from 4.1 nm to 4.8 nm from 0.14 mg/ml to 0.55 mg/ml, and L increases from 17 nm to 19 nm. (c) For primarily dimeric SCR-16/20 at 0.72 mg/ml, 0.86 mg/ml and 1.15 mg/ml, M ranges from 5.1 nm to 5.8 nm and L ranges from 25 nm to 27 nm.
