Document Summary

All figures from lecture 4 slides of p. gooley, melbourne university, march 2017 (unless stated otherwise) 4 atoms and 3 bonds are part of the dihedral angle. The box is around the 4 atoms, as it is shifted from left to right, the next 2 dihedral angles are defined. Looking at dihedral angles giving definition of the shape of the main chain of the protein in torsion space. Looks like free rotation around the n c bond. the dihedral angle here is 179. 9o = tra(cid:374)s (cid:664) Each residue now can be characterised by a and pair. The and torsion angles of a protein are not completely free to rotate, they are restricted because of steric clashes. Pi angles on negative size, whereas psi is both. Each spot represents the pi-psi pair of a single residue. If the pi-psi angles of every non-glycine residue of all proteins of known structure were plotted in a.
