Fig. 5: Size exclusion chromatography elution profile of PaqFOS1 monitored at 280, 254, and 450 nm corresponding to absorbance (mAU) of the polypeptide, NADPH, and FAD, respectively.

Based on the elution volume in comparison to a set of reference proteins with known molecular masses, the PaqFOS1 protein eluted as a dimer with a mass of ~120 kDa. SDS-PAGE analysis of the PaqFOS1 containing fractions obtained by size exclusion chromatography demonstrating that PaqFOS1 migrated with an apparent molecular mass of 60 kDa in agreement with a calculated molecular mass of 62.5 kDa for the monomeric protein.
