N2 - The acidic ferric form of hemoglobin and myoglobin carries a water molecule as the sixth ligand of the iron atom. On the other hand, Aplysia met myoglobin shows a pentaco-ordinated active site below the pK of the acid-alkaline transition (7.5). This finding rationalizes some peculiar properties of Aplysia myoglobin as compared with sperm whale myoglobin.
