Abstract
Diffraction data to 2.7 angstrom resolution were measured on crystals of the homotetramers of components II and III of the cytoplasmic hemog lobin of the symbiont-harboring clam Lucina pectinata. Even though the crystallization conditions are different and the sequence homology of the two hemoglobins is only 63%, the crystals are isomorphous to each other and to the heterotetramer Hb II/III, implying that the residues primarily involved in the intermolecular interactions and responsible for crystal cohesion may be invariant.
