Geis highlights the hundreds of chemical bonds in the lattice of myoglobin.

Myoglobin Fold

Geis illustrated the structure of myoglobin, focusing on the folding pattern of the secondary structure of the protein. Unlike previous myoglobin Illustrations, this painting focuses on the tertiary structure of the molecule rather than the sequence or surface.


Geis illustrates the hemoglobin molecule as four symmetrically arranged myoglobins. Since it is responsible to the transport of oxygen, it can change from an oxygen-binding configuration to an oxygen-releasing configuration in response to the demand for oxygen.


The colored print depicts the structure of myohemerythrin, which was first revealed by X-ray crystallography in 1975 (Hendrickson et al., 1975) and further refined in 1987 (Sheriff et al., 1987). Geis's illustration depicts the tertiary structure of the protein, highlighting the four anti-parallel alpha-helices and the presence of mu-oxo-diiron (iron atoms in red and oxygen atom in pink) located within the core of the macromolecule (Myohemerythrin).
