| Protein complex | Elution volume [ml] | ExperimentalSEC# molecular weight [kDa] | ExperimentalSLS& molecular weight [kDa] | ExperimentalSG* molecular weight [kDa] | Theoretical§ molecular weight [kDa] |
|---|---|---|---|---|---|
| RPA | 1.63 ± 0.02 | 110 | 106 ± 6 | N.D. | 96.2 |
| Tim-Tipin | 1.46 ± 0.01 | 321 | 164 ± 12 | 158 | 162.3 |
| Tim-Tipin-RPA | 1.43 ± 0.02 | 388 | 273 ± 31 | N.D. | 258.5 |
#Molecular weights derived from SEC were estimated based on the comparison with molecular mass standard proteins.
&Molecular weights determined by SLS.
*Molecular weight determined by sucrose-gradient sedimentation assay (SG).
§Molecular weights calculated based on the amino acid sequence.
N.D. = not determined.
