2GTL - PubMed Abstract: 
Annelid erythrocruorins are highly cooperative extracellular respiratory proteins with molecular masses on the order of 3.6 million Daltons. We report here the 3.5 A crystal structure of erythrocruorin from the earthworm Lumbricus terrestris. This structure reveals details of symmetrical and quasi-symmetrical interactions that dictate the self-limited assembly of 144 hemoglobin and 36 linker subunits ...
