3791352-1	1986	Myoglobin, an intracellular iron containing protein that binds oxygen reversibly, has been shown in model systems to facilitate the diffusion of oxygen and thereby maintain the mechanical function of exercising canine skeletal muscle and of hypoxic benthic fish hearts.	Iron	28-32	myoglobin	Canis lupus familiaris	0-9	
21498596-2	2011	Iron is used in the formation of both hemoglobin and myoglobin, as well as numerous enzyme systems of the body.	Iron	0-4	myoglobin	Canis lupus familiaris	53-62	
2808397-5	1989	Activation volumes for O2 to the iron binding step as well as for the O2 diffusion step within the protein matrix were quite different among three Mb species, and it was suggested that activation volumes are very sensitive to the amino acid constituents around the ligand path channel.
