An X-ray study of horse methemoglobin. A complete three-dimensional Patterson synthesis of haemoglobin has been calculated, giving the distribution of vector density in thirty-one sections through the unit cell. The sections show certain concentrations of vector density which can be interpreted in terms of polypeptide chain structure. The following are the conclusions tentatively arrived at on the evidence described in this paper. The haemoglobin molecule resembles a cylinder of 57 angstrom diameter and 34 angstrom height, which consists of an assembly of polypeptide chains running parallel to the base of the cylinder. The chains s...
