Conference paper


Electron microscopy of earthworm erythrocruorin shows two hexagonal rings stacked on one another (1–5). Existing models of the molecule involve 12 identical subunits arranged in dihedral symmetry (6–10). In the present report, the adequacy of this model to account for the dissociation pattern of earthworm erythrocruorin is examined. A new model is proposed.
