This technology estimates highly active variants through the analysis of enzymes using molecular dynamics (MD) simulations.

Research Contents

In this research, we worked on designing highly active enzyme variants using MD simulations.

By analyzing the orientation and movement of the substrate near the activation site of an enzyme by simulations, we predicted variants that are likely to be highly activated.
We have experimentally confirmed that the fraction of reaction products is improved up to 8.6 times and the reaction volume is improved up to 6.3 times, using the variants designed by this method.

Strengths in the Industrial Arena

This method can be applied to any enzyme whose three-dimensional conformation has been determined.
