Erythrocruorins are giant extracellular respiratory proteins found freely dissolved in the blood of annelids. We present here results from our ultracentrifugation, electron microscopy, spectroscopy, and diffraction experiments on these erythrocruorins. These data are rationalized in terms of a three-dimensional model of the quaternary structure. The proposed structure is arranged in a hierarchy of symmetry. The implications of this structure for the assembly process are considered with special attention to uniqueness and self-limitation. The hypothesis is consistent with observations not used in its construction and it serves as a working hypothesis to focus further experimentation.
