Computer approaches to protein structure III. Transformation of atomic coordinates☆
Review articleOpen access
Abstract:

AbstractThe study of polypeptide and protein structure with computer-generated molecular models provides numerous advantages over conventional framework molecular models. One notable advantage is the dynamic nature of the computer model. Computer programs, discussed in this report, transform the coordinates of atoms of a peptide or protein, resulting in the rotation of the molecule about a fixed reference point in the x-y or y-z planes. The angle of rotation is increased by 5° after each structure is drawn on the cathode ray tube. As a result, for one complete revolution of the molecule, the computer draws 72 different images and the cathode ray tube is photographed to provide a permanent record of each structure.
