Consequences of Mutations

Concept Check: Based on the fiber-like structures seen in part (c) of this figure, what aspect of hemoglobin structure does a glutamic acid at the sixth position in normal β-globin prevent? Speculate as to how the charge of this amino acid may play a role.

The distal Histidine (His 64) in myoglobin is subjected to three different mutations, this is one of them: H64N. (Histidine to Aparagine)   For the mutation, draw a theoretical binding curve and CO relative to the O2 and CO binding curves for wild-type Mb (see example below). Provide a clear rationale for the binding curve.
Question:- What biological rationale can explain why there are so few variants observed at position 65 of the heme distal ligand and position 94 of the heme proximal ligand of myoglobin? Why does the number of variants differ between the two sites?
