Ribbon drawing of triose phosphate isomerase 3D protein structure
Ribbon schematic (hand drawn ink outline, colored in pastels, 1981) of the 3D structure of the protein triose-phosphate isomerase. The barrel of 8 beta-strands is shown by green arrows and the 8 alpha-helices as brown spirals. One of about 75 ribbon drawings created by Jane Richardson to illustrate "The Anatomy and Taxonomy of Protein Structures" Advances in Protein Chemistry vol. 34, pp 167-339.
