METHOD AND DEVICE FOR CALCULATING OPTIMIZATION SOLUTION OF MULTIPLE MUTANT PROTEIN AMINO ACID SEQUENCE, AND STORAGE MEDIUM WHERE PROGRAM FOR EXECUTING THE METHOD IS STORED

Document Type and Number:

WIPO Patent Application WO/2001/048640

Kind Code:

A1

Abstract:

A method for calculating the solution of optimization of a multiple mutant protein amino acid sequence, comprises a step of seeking the amino acid side chain three-dimensional structure coordinates of the amino acid sequence of each of the members of a multiple mutant protein group on the basis of the three-dimensional structure data on a template protein group according to a dead end elimination algorithm and calculating the minimization of the structure energy of the member to calculate the optimum three-dimensional coordinates of the multiple mutant protein, a step calculating the characteristic value from the optimum three-dimensional structure coordinates, and a step of calculating the member that optimizes the characteristic value by applying a genetic algorithm to the multiple mutant protein group. From the multiple mutant protein group including a vast number of combinations, the solution of optimization is selected on the basis of the characteristic value in a short time without degrading the accuracy.
