Prediction of Protein Backbone Torsion Angles Using Deep

WebBackbone angles in a protein are dihedral angles, which are the angles between two intersecting planes. They're also referred to as torsion angles, referring to how part of the backbone rotates or twists twists with regard to another part. The most important backbone angles are phi (φ) and psi (ψ). These angles are plotted on the Rama map. WebThe Ramachandran plot is the 2d plot of the ϕ-ψ torsion angles of the protein backbone. It provides a simple view of the conformation of a protein.
