Understanding of Kinematic Structures of Proteins for Performing Functions from a View Point of Robot Kinematics

From a perspective of robot kinematics, we proposed a protein model which comprises serial link manipulators constrained by springs, and a method for analyzing the characteristics of the internal motion. We applied this method to data from PDB of a variety of proteins. The results are almost consistent with the actual internal motions of them in performing functions. The kinematic structures of proteins for performing functions are represented in the model and the analysis.
