Abstract

Motivation: Poor protein solubility hinders the production of many therapeutic
and industrially useful proteins. Experimental efforts to increase solubility are
plagued by low success rates and often reduce biological activity. Computational
prediction of protein expressibility and solubility in Escherichia coli using
only sequence information could reduce the cost of experimental studies by
enabling prioritisation of highly soluble proteins. Results: A new tool for
sequence-based prediction of soluble protein expression in Escherichia coli,
SoluProt, was created using the gradient boosting machine technique with the
TargetTrack database as a training set. When evaluated against a balanced
independent test set derived from the NESG database, SoluProts accuracy of 58.4%
and AUC of 0.60 exceeded those of a suite of alternative solubility prediction
tools. There is also evidence that it could significantly increase the success
rate of experimental protein studies. SoluProt is freely available as
a standalone program and a user-friendly webserver at
https://loschmidt.chemi.muni.cz/soluprot/.
