Figures:
FoldIndex prediction results of 1-24 recombinant proteins listed in Table 2. The subtitle of soluble recombinant proteins expressed in the laboratory were highlighted.
ROC analysis of some features (MW, helix, pI, aliphatic, GRAVY, FoldIndex) and PSoL for predicting the solubility of recombinant proteins expressed in E. coli . The area under the ROC Curve scores (perfect = 1:00, random = 0:50) are shown in parentheses. ROC: Receiver operating characteristic, MW: molecular weight, helix: the percentage of helix structure, pI: pH isoelectric, GRAVY: grand average of hydropathy.
