This image is Figure 1 in our paper. It shows the structure of myoglobin, which became the first known structure of a globular protein, obtained by Kendrew and co-workers in 1958. The structure is of low resolution, but its lack of regularity helped launch the field of protein folding. Since 1958, more than 80,000 protein structures have been determined at much higher resolution.
