Transcribed Image Text:Which one of the following choices contains ONLY TRUE statements?
O The active site of myoglobin contains a haem prosthetic group. The propionate substituents on the porphyrin
ring are involved in hydrogen-bonding interactions with water molecules. In deoxymyoglobin the haem group
contains Fe(l) in the high spin state. Upon binding dioxygen the iron undergoes a change in spin state that
reduces its ionic radii inducing a structural change in the protein.
O The active site of myoglobin contains a haem group. The propionate substituents on the porphyrin ring are
used to form amide bonds with lysine residues on the protein. In deoxymyoglobin the haem group contains
Fe(ll) in the low spin state. Upon binding dioxygen the iron undergoes a change in spin state that reduces its
ionic radii inducing a structural change in the protein.
