  1. Resource Description
    "Analyzing the motion of flexible protein loops is becoming increasingly important in understanding the various roles that proteins play in human body. LoopTK is a C++ based object-oriented toolkit which models the kinematics of a protein chain and provides methods to explore its motion space. In LoopTK, a protein chain is modeled as a robot manipulator with bonds acting as arms and the dihedral degree of freedoms acting as joints. LoopTK is designed specifically to model the kinematics of protein loops, but it can be used to analyze the motion of any part of the protein chain. LoopTK provides methods for sampling the conformation space of protein loops as well as the self motion space of a loop. Example applications for LoopTK include x-ray crystallography, homology modeling, and drug design. LoopTK was developed in close collaboration with the Joint Center for Structural Genomics (JCSG) at the Stanford Linear Accelerator Center. Now a part of the JCSG's protein structure determination process, loopTK models missing protein fragments into experimental data (http://smb.slac.stanford.edu/XpleoServer/Xpleo.jsp). This material is based upon work supported by the National Science Foundation under Grant No. 0443939.
