A Perspective on Bionanosensor Simulation & Computational Enzyme Engineering

Martin Robert Hediger

Abstract

This essay describes the work of two projects. The first project, Bionanosensor Simulation, describes design and implementation of a new web interface which allows to carry out simulations of a protein sensor conveniently and fast. Out of all biosensor simulation programs, our program is the rst which displays the proteins threedimensionally in a web browser. This can be applied to the study of how the orientation of a protein a affects the electric current which runs through the sensor. These changes in current allow to detect proteins of extremely low concentrations and our simulation program helps in optimizing such sensors. In the second project, Computational Enzyme Engineering, a method is developed which can be used to calculate the reaction barrier of a large number of enzyme mutants. First technical details are discussed, then we compare to experiments from Novozymes A/S and show how accurate the method is. Finally we use the method to calcualte the rate-limiting step in the reaction profile of around 400 mutants of an enzyme. This is the first time that the barrier of the rate-determining step is alculated in as set of mutants of this size, consisting of the full enzyme structure and with a solvation model applied.
