2.2 Solubility

Data name Solubility
Description of data contents The solubilities of individual proteins were evaluated by using a cell-free translation system (PURE system) which is chaperone-free.
The data of chaperone effects on the prevention of aggregate formation are available for 788 aggregation-prone proteins.
The concentrations of chaperones were as follows:
- TF (Trigger factor): 5.0 (monomer) μM
- GroE (GroEL and GroES): 0.5 (tetradecamer) and 1.0 (heptamer) μM
- KJE (DnaK, DnaJ and GrpE): 5.0 (monomer), 2.0 (monomer), and 2.0 (monomer) μM
