A, molar mass measured by multi-angle light scattering after gel filtration for EcDos (5 μm) using SEC-MALL. B, correlation between hydrodynamic diameters (measured by dynamic light scattering, Malvern Instrument and Wyatt Technology) and the molar mass of six globular proteins (○). FixLH hydrodynamic diameters (monomeric, 0.5 μm; dimeric, 25 μm) (●) fit well with the hydrodynamic diameters of globular proteins, whereas monomeric (0.5 μm) and dimeric (30 μm) EcDosH PAS (▴) and full-length EcDos (■) hydrodynamic diameters deviate from the correlation line.
