WebProtein backbone torsion angles (Phi) and (Psi) involve two rotation angles rotating around the C (α)-N bond (Phi) and the C (α)-C bond (Psi). Due to the planarity of the linked rigid... WebThe backbone structure of a protein is largely determined by the phi and psi torsion angles. Thus, knowing these angles, even if approximately, will be very useful for protein-structure prediction. However, in a previous work, a sequence-based, real-value prediction of psi angle could only achieve a …

WebSep 4, 2024 · What are the φ phi and ψ psi angles? As with any peptide the conformation of the backbone is determined by the values of two torsional angles. In sequence order, phi (φ) is the C (i-1),N (i),Ca (i),C (i) torsion angle and psi (ψ) is the N (i),Ca (i),C (i),N (i+1) torsion angle. What is phi and psi bond? Each peptide bond holds six atoms in a plane. WebUnderstanding the torsion angles will help to understand the protein structure. In this tutorial, it is clearly explained how to calculate torsion angles of a protein using PyMol. As...
WebTo measure the phi torsion angle click on C'-N-Calpha-C' in a peptide backbone. You always have to click on 4 atoms, since you want to measure between 2 planes. ... for computing the phi/psi ...
