Versatile Interactive Graphics Display System For Molecular Modeling By Computer

THE intricacies of constructing molecular models of macro-molecules based on coordinates determined by X-ray crytallography has become a major task in itself, particularly now that a large number of protein structures has been determined. The combination of a computer and a graphics display terminal can be a powerful tool in studies of macro-molecules. Several computer-based systems for the display of molecular structures have been described which differ greatly1–5 and it was recently suggested that smaller computers can provide adequate capability6.
