Series contains figures, sketches, photographs, and drawings pertaining to the Richardson's work on the structure of copper, zinc superoxide dismutase, an enzyme that protects all living things against the toxicity of oxygen. The Richardson's began working on this structure when they arrived at Duke the 1969. Series includes figures from the 1982 article "Determination and analysis of the 2 A structure of copper, zinc superoxide dismutase," coauthored with John A. Tainer. Series also contains figures from the 1976 article "Similarity and Three-dimensional Structure Between the Immunoglobulin Domain and the Copper, Zinc Superoxide Dismutase Subunit." Materials date from 1973 to 1982, a significant amount being undated.
