Side Chain Kinematics Simulation on Protein Conformational Changes
Protein simulation remains as one of the most difficult task for biologists, physicists or engineers. The huge computational requirements of the protein models makes it difficult to obtain simulations of big conformational changes on protein structure. Side chain modelization is a critical step when obtaining the protein structure model. The time scale at which side chain movement occur can greatly increase the computational cost of the process. In this paper, we propose a side chain orientation procedure with a very low computational cost. This procedure has been implemented in combination with other procedures to obtain a computationally efficient simulation tool for protein simulation. This simulation tool has been used to simulate several protein conformational changes with success.
