Abstract
At the 3rd Hemocyanin Meeting in Louvain, Mellema showed a model for a gastropod hemocyanin based on three-dimensional reconstruction from electron micrographs (Mellema and Klug, 1972). The cylindrical molecule has 52 symmetry and consists of a wall, two collars and two caps. The wall contains 60 morphological units with dyad symmetry bounded by two sets of helical grooves. The morphological units are of six crystallographic distinct types, but they are similar in size, shape and orientation. Each collar contains five blobs of material. The cap has no substructure.
