Amino acid sequence of the monomer subunit of the extracellular hemoglobin of Lumbricus terrestris.


The giant extracellular hemoglobin (3,800 kDa) of the oligochaete Lumbricus terrestris consists of four subunits: a monomer (chain I), two subunits each of about 35 kDa (chains V and VI), and a disulfide-bonded trimer (50 kDa) of chains II, III, and IV. The complete amino acid sequence of chain I was determined: it consists of 142 amino acid residues and… (More)
