In Side Chain Refinement step, A side chain can be built by searching every possible conformation at every torsion angle of the side chain to select the one that has the lowest interaction energy with neighboring atoms.

Tertiary protein structure prediction is computational elucidation of the three-dimensional structure of a protein for which experimentally determined structure is unavailable from its amino acid sequence.

Topic include: Ab Initio Protein Structural Prediction & Homology Modeling, & Threading and Fold Recognition.
