Myoglobin was the first protein to have its three-dimensional structure determined by X-ray crystallography: Kendrew JC, Bodo G, Dintzis HM, Parrish RG, Wyckoff H, Phillips DC (1958) A Three-Dimensional Model of the Myoglobin Molecule Obtained by X-Ray Analysis. Nature 181(4610): 662-6. For this achievement, John Kendrew shared the 1962 Nobel Prize in chemistry with Max Perutz. http://www.nobelprize.org/nobel_prizes/chemistry/laureates/1962/ "Myoglobin is an iron- and oxygen-binding protein found in the muscle tissue of vertebrates in general and in almost all mammals." --http://en.wikipedia.org/wiki/Myoglobin One STL file contains a representation of the protein in cartoon form with residues binding the heme group represented as spheres (in green in the images). A separate STL file contains the heme group itself (in red in the images).
