If we are to understand the functions and mechanisms of proteins, we must know their atomic structures. To help in the process of modelling structures of proteins, the Unit has two state-of-the-art desktop stereographic 3D displays and a bespoke 93" stereographic 3D projection system for the visualisation of protein structures. They are especially useful in the manual refinement of atomic models from X-ray crystallography and the docking of ligands to protein molecules.
