ESPRESSO (EStimation of PRotein ExpreSsion and SOlubility) is a sequence-based predictor for estimating protein expression and solubility.

ESPRESSO provides useful information to the two questions.
1. Can a sequence be expressed in Escherichia Coli expression system?
Can a sequence be contained in soluble fraction in Escherichia Coli expression system, wheat germ cell-free system, and Brevibacillus expression system?
2. Which sequence should be modified to improve protein expression/solubility ?
3. Which amino acid in a sequence should be mutated to improve protein expression/solubility ?
(This function is supported by the motif based prediction.)



All the users (including academic users and profit users) can use ESPRESSO for free.
